Answer:

b) -12 , -8 , -4, 0

Step-by-step explanation:

-12 + 4(n - 1)

n means the term

place the values of  1, 2, 3 and 4

-12 + 4(1-1) = -12

-12 + 4(2-1) = -8

-12 + 4(3-1) = -4

-12 + 4(4-1) = 0

hence the answer is

b) -12 , -8 , -4, 0

Answer:

3

Step-by-step explanation:

We know that m= -3 so we plug it into our equation

[tex]-3^{2}[/tex]+5*-3+9

NOTE: in an equation when a letter is touching a number that means to multiply, that's how i got 5*-3 in the equation.

Now we solve!

[tex]-3^{2}[/tex]+5*-3+9 = 3

Answer:

x=1±i√5

Step-by-step explanation:

the quadratic equation is in the form :

y=ax²+bx+c

y= 2x²-4x+12

x=(-b±√b²-4ac)/2a

x=-(-4)±√-4²-4(2)(12)/2a

x=4±√16-96/4

x=4±√-80/4

since the number under the square root then √-80=4i√5 ( assuming possitive numbers)

x=(4±4i√5)/4

x=4(1±i√5)/4

x=1±i√5

Answer:

956300000000

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.  9.563  ×  10 ^11

The result can be shown in multiple forms.

Answer:

Length side is 3 cm

Step-by-step explanation:

the length in square is called side.

A= sides X sides

9 = s^2

S= 3

Just copy and paste "learningandassignments diy4pro" to google search engine.

Hope it helps.

Value of side length is 3 cm

Give that;

Area of square = 9 cm²

FInd:

Value of side length

Computation:

We know that,

⇒ Area of square = Side²

BY putting value into formula

⇒ Side² = 9

⇒ Side² = 3²

⇒ Side = 3

So,

Value of side length = 3 cm

Answer:

21

Step-by-step explanation:

there are 7 students and 3 prizes so all you needed to do was multiply 3 by 7 or 7 by 3.

Answer:

35 different ways!

Step-by-step explanation:

7! / 3! * (4!)

If you know combinations and permutations, then the above formula will make sense.

Since this question is asking for all possible combinations, it's this formula if you don't know it:

n! / r! (n - r)!

n is the total number of things, which in this case are people. So, we get 7 and r is the set amount of the things used at a time which is 3... because out of 7 people only 3 can win gift cards.

Hi there! :)

a) (ii) The two angles are vertical angles, so they are congruent.

b)(i) y = 71°

  (ii) The two angles are alternate interior angles, so they are congruent.

c) z = 44°

(ii) m∠x = 65° because the two angles are vertical angles, so they are congruent.

b) (i)

∠y is an alternate interior angle, therefore:

m∠y = 71°

c) Use the sum of interior angles of a triangle to determine the measure of angle z:

180 = 65 + 71 + z

180 = 136 + z

180 - 136 = z

z = 44°.

Answer:

C. -25

Step-by-step explanation:

Since the current number is -55, it depicts the number to achieve the target.

That is the current position states that we require 55 more units to produce.

If we produce 30 more units in an hour, we shall require 55 - 30 = 25 more units to produce, in order to achieve target.

Since target is decreased by 30, but yet not achieved completely it will still be a negative number.

Thus, the correct answer is

C. -25

This depicts that achieved volume of units is short by 25 units in order to achieve the target.

Hi!

Your answer should be: -2x= 10

Reason being: -2+3= 0

So this must mean: x=10

Because 10+3=13

Hope this helps!

Yours truly,

Answer:

x = -5

Step-by-step explanation:

-2x = 13-3

-2x = 10

x/-2 = 10/-2

x = -5

Answer:

2x + 5 = 13

take away 5 from both sides

2x = 8

divide both sides by 2
