Step by step on how to solve this equation 2 x + 3 = x − 4 because I fogot how to do basic math

Answer:

h=9cm

P=(x+5)cm

b=(x-3)cm

by the Pythagoras theorem,

h^2=p^2+b^2

9^2=(x+5)^2+(x-3)^2

81=x^2+10x+25+x^2-6x+9

81=2x^2+4x+34

Answer:  142 and 286

==========================================

Explanation:

If we multiply a given term by 2, then add 2, we get

7*2+2 = 14+2 = 16

16*2+2 = 32+2 = 34

34*2+2 = 68+2 = 70

So the rule seems to be "multiply by 2, then add 2"

If that rule holds up, then the next two terms are

70*2+2 = 140+2 = 142

142*2+2 = 284+2 = 286

The opposite of 0.75 is -3/4.

To get a result equal to 0, add the original number and the additive inverse by simply changing the sign of the integer. On the basis of negation of the original number, the characteristics of additive inverse are listed below.

Given:

we have 0.75

So, to find the opposite we have to find the additive inverse of 0.75

Then, the additive inverse of 0.75 is (-0.75).

Then, -0.75 = -3/4.

Hence, the opposite is -3/4.

Answer:

957

The answer is this because the next 3 digit multiple of 33 would be 990.

Answer:

The answer is 957.

Step-by-step explanation:

Figure out how high one can go (multiplying by high numbers) without going into the 4-digits. Then, work backwards from there.

33*30 = 990

33*29 = 957

Answer:

"If the shape is not a rectangle, then the shape doesn't has four sides."

Step-by-step explanation:

Given conditional statement is,

" Is a shape has four sides, then the shape is a rectangle."

Here we have two statements:

Statement p → A shape has four sides

Statement q → The shape is a rectangle.

Contrapositive of the statement will be:

If [tex]\sim q[/tex] then [tex]\sim p[/tex].

Therefore, contrapositive will be,

"If the shape is not a rectangle, then the shape doesn't has four sides."

Answer:

x²

Step-by-step explanation:

Given the values x² and x^9

The greatest common factor is the factors common to two or more compared values :

Factors of :

x² = x * x

x^9 = x * x * x * x * x * x * x * x * x

Multiplying the Factors in both are : x * x = x²

Similarly :

___|x² | x^9

_ x | x | x^8

_ x | 1 | x^7

There is no factor which can reduce both further simultaneously, Hence the G. C. F = (x * x) = x²

Answer:

The plane was traveling at 800 mph

Step-by-step explanation:

Step 1: Find the total number of minutes flown by airplane

         3 hours * 60 minutes/hour = 180         180 + 33 = 213 total minutes

Step 2: Divide the number of miles flown by the number of minutes

                2840 miles / 213 minutes = 13.3333333 miles/minute

Step 3: Multiply the number of miles/minute by 60 to calculate the number of miles/hour

                    13.3333333 miles/minute * 60 minutes/hour = 800 miles/hour

Answer:

Step-by-step explanation:

Given :

l + m + n = 9

l²+ m² + n²= 31

l + m + n = 9

On squaring both sides

(l + m + n)²= 9²

(l²+m²+n²+2(lm+mn+nl) = 81

31 +2(lm+mn+nl) = 81

2(lm+mn+nl) = 81 - 31

2(lm+mn+nl) = 50

(lm+mn+nl) = 50/2

(lm+mn+nl) = 25

Hence, the value of (lm+mn+nl) = 25

Answer:

40 degrees

Step-by-step explanation:

the three angles of a triangle must add to 180 and since it is an isosceles two angles must be equal therefore 180-100=80 to be divided by 2.

Answer:

Step-by-step explanation:

Given the height of a golf ball in feet modelled by the formula h(t) = -16t² + 100x where t is in seconds, we are to find the height of the golf after 2.5 seconds. To do that we will simply substitute t = 2.5secs into the formula given;

[tex]h(t) = -16t^2 + 100x\\\\h(2.5) = -16(2.5)^2 + 100(2.5)\\\\h(2.5) = -16(6.25) + 250\\\\h(2.5) = -100+250\\\\h(2.5) = 150\\\\[/tex]

Hence the height of the golf after 2.5 seconds is 150ft.
