How do you find area and perimeter of a rectangle with the side lengths of 5x^2 and 12x?

Answers

Answer 1

Answer:

The area can be found by multiplying the two terms, and the perimeter by doubling and adding them.

Using this, we find that the area of the rectangle is 60x³, and the perimeter is 10x² + 24x.

Step-by-step explanation:

First let's find the area:

5x² × 12x

= 60x³

Now the perimeter:

2(5x² + 12x)

= 10x² + 24x

mean and the median of the data.

Answers

Answer:

12

Step-by-step explanation:

12 doesn't fit the data because it is so much farther from the general average of the others.

12 affects the median because with it, the median is 74. but without 12, the median is 76.

12 affects the mean because with it, the mean is 68.36. but without 12, the mean is 72.69.

Jenna earns $8 each week by completing chores. She already has $12 in her savings. How much will she have after 4 weeks?


y = 8x + 4


y = 8x


y = 8x + 12

Answers

Answer:

Option C is the correct answer.

Step-by-step explanation:

Per week earning = $8

Amount in savings = $12

y = Total amount

x = Number of weeks

y = 8x + 12

Where we can put x=4 to calculate earning of 4 weeks.

y = 8(4) + 12

y = 32 + 12 = $44

Therefore,

Answers

x2+2x-15=0
2x+2x-15=0
4x-15=0
4x=15
so answer is x= 15/4

Answer:

x = - 5, x = 3

Step-by-step explanation:

Given

x² + 2x - 15 = 0

Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)

The factors are + 5 and - 3 , since

5 × - 3 = - 15 and 5 - 3 = + 2, so

x² + 2x - 15 = 0

(x + 5)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 3 = 0 ⇒ x = 3
