Answer:

g^2 + 4

I literally do not know how to explain it. I solved this problem with the clues like sum and squared. I looked at where these words were located.

The algebraic expression for the sum of g squared and four is g^2 + 4.

The given statement is "the sum of g squared and four".

We need to write an algebraic expression for this statement.

- Sum = add = +

- Difference = minus = -

- Divide = ÷

- Squared = [tex]x^{2}[/tex]

- cube = [tex]x^{3}[/tex]

- Square root = [tex]\sqrt{x}[/tex]

We have,

"the sum of g squared and four".

Let us separate it into two parts:

g squared - [tex]g^{2}[/tex]

Four = 4

Sum = +

So we have,

Sum of g squared and four = [tex]g^{2}[/tex] + 4.

Thus the algebraic expression for the sum of g squared and four is  [tex]g^{2}[/tex] + 4.

Answer:

x=26

Step-by-step explanation:

exterior angles theorem meaning they're equal to each other.

5x+7=8x-71

add 71 to 7

5x+78=8x

subtract 5x from 8x

78=3x

divide 78 and 3

x=26

to check your work plug 26 into each equation:

5(26)+7= 137°

8(26)-71= 137°

because they're the same you know that x must equal 26

Answer:

14x-85

Step-by-step explanation:

The area of the shaded region is

[tex](x + 6)(x - 6) - {(x - 7)}^{2} [/tex]

which if you use the identities to expand it gives you

[tex] {x}^{2} - 36 - {x}^{2} + 14x - 49[/tex]

This then reduces to be

[tex]14x - 85[/tex]

Answer:

a) Beatriz: [tex]y = 3\cdot x[/tex], Jesús: [tex]z = 5\cdot x[/tex], b) [tex]y+z = 32[/tex], c) El símbolo (edad de Rocío) queda representado en el siguiente factor común: [tex](3+5)\cdot x = 32[/tex], d) Rocío tiene 4 años de edad, Beatriz tiene 12 años de edad y Jesús tiene 20 años de edad.

Step-by-step explanation:

a) Sean [tex]x[/tex], [tex]y[/tex], [tex]z[/tex] las edades de Rocío, Beatriz y Jesús. Después de una lectura cuidadosa al enunciado:

(i) Beatriz tiene el triple de la edad de Rocío.

[tex]y = 3\cdot x[/tex] (Ec. 1)

(ii) Jesús tiene cinco veces más años que Rocío.

[tex]z = 5\cdot x[/tex] (Ec. 2)

b) Seguimos la misma estrategia del punto a):

Entre Beatriz y Jesús suman 32 años.

[tex]y+z = 32[/tex] (Ec. 3)

c) Sustituimos [tex]y[/tex], [tex]z[/tex] en (Ec. 3):

[tex]3\cdot x + 5\cdot x = 32[/tex]

[tex](3+5)\cdot x = 32[/tex]

[tex]8\cdot x = 32[/tex]

[tex]8\cdot x = 8\cdot 4[/tex]

[tex]x = 4[/tex]

El símbolo (edad de Rocío) queda representado en el siguiente factor común: [tex](3+5)\cdot x = 32[/tex]

d) Tal como desarrollamos en el punto c), Rocío tiene 4 años de edad.

Las edades de Beatriz y Jesús se obtiene por sustitución directa:

Beatriz

[tex]y = 3\cdot x[/tex]

[tex]y = 3\cdot 4[/tex]

[tex]y = 12[/tex]

Beatriz tiene 12 años de edad.

Jesús

[tex]z = 5\cdot x[/tex]

[tex]z = 5\cdot 4[/tex]

[tex]z = 20[/tex]

Jesús tiene 20 años de edad.

Answer:

140.25°

Step-by-step explanation:

Angle 1 and Angle (3x+12) share the exact same angle since they are congruent. Knowing this, you can replace angle 1 with (3x+12). Math tells you that supplementary angles are two angles that add up to 180 degrees.

(x-3) and (3x+12) are supplementary. Since they are supplementary and math tells me that two angles add up to 180. I can add (x-3) and (3x+12). But to finish the equation, both of these angles must equal 180.

Your equation should look something like this (it should look like this):

[tex](x-3)+(3x+12)=180[/tex]

From there you can simplify and isolate the x value to solve for x. Your x value is 42.75. But, we are not done here.

Now that we know x, which is just a placeholder, we must replace the placeholder with its actual numerical value (42.75).

3(42.75) + 12 = 140.25.

To make sure both angles equal up to 180.

Replace all x's with 42.75 and you will see that they equal 180.

[tex](3(42.75)+12)+(42.75 - 3) = 180[/tex]

[tex]180=180[/tex]✅

The solution of the given expression [tex](64)^\frac{1}{2} \times 10^{-2}[/tex] will be 2 / 25.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is [tex](64)^\frac{1}{2} \times 10^{-2}[/tex] . The solution of the expression is done as below:-

E = [tex](64)^\frac{1}{2} \times 10^{-2}[/tex]

E = √64 x 10⁻²

E = 8 x 10⁻²

E = 8 / 10²

E = 8 / 100

E = 2 / 25

Therefore, the solution of the given expression [tex](64)^\frac{1}{2} \times 10^{-2}[/tex] will be 2 / 25.

One solution was found :

Answer:

x = 1.5

Step-by-step explanation:

Step 1: you distribute what is on the outside of the parenthesis to EVERYTHING on the inside of the equation which will leave you with

7x-14-3x+5=-10x+8+4

Step 2: Combine your like terms. You have to add all the X's on the left side first, then your whole numbers. After that, you go to the right side and do the same thing. This should leave you with    4x-9=-10x+12

Step 3: get x to one side of the equation. You do the opposite of what the x is on the right. So you would add 10x on both sides. This should leave you with 14x-9=12

Step 4: You do the opposite of the whole number on the left to both sides/ add 9 to both sides. This should leave you with 14x=21

Step 5: you now divide both sides by 14 because 14x is a multiplication problem, and you need to do the opposite. So you should finally get

X=1.5

Answer:

[tex]t = 1.71825[/tex]

Step-by-step explanation:

Given

[tex]h(t) = -16t^2 + 24t + 6[/tex]

Required

When will the coin hit the ground

When the coin hits the ground, [tex]h(t) = 0[/tex]

The expression [tex]h(t) = -16t^2 + 24t + 6[/tex] becomes

[tex]0 = -16t^2 + 24t + 6[/tex]

Multiply through by -1

[tex]16t^2 - 24t - 6 = 0[/tex]

Solve using quadratic formula

[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]

Where

[tex]a = 16[/tex]

[tex]b = -24[/tex]

[tex]c = -6[/tex]

[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]

[tex]t = \frac{-(-24)\±\sqrt{(-24)^2 - 4 *16 * -6}}{2 * 16}[/tex]

[tex]t = \frac{24\±\sqrt{576 +384}}{32}[/tex]

[tex]t = \frac{24\±\sqrt{960}}{32}[/tex]

[tex]t = \frac{24\±30.984}{32}[/tex]

Split

[tex]t = \frac{24+30.984}{32}[/tex] or [tex]t = \frac{24-30.984}{32}[/tex]

[tex]t = \frac{54.984}{32}[/tex] or [tex]t = \frac{-6.984}{32}[/tex]

[tex]t = 1.71825[/tex] or [tex]t = -0.21825[/tex]

But time can't be negative;

Time to hit the ground is 1.71825 seconds

x = - 27

Step-by-step explanation:

Hi !

- 0.45x + 0.15 = 8.1

- (0.45x - 0.15) = 8.1

- (0.30x) = 8.1

- 0.3x = 8.1

x = 8.1 : (- 0.3)

x = 81/10 : (-3/10)

x = 81/10 × (-10/3)

x = - 81/3

x = - 27
