The sum of 3 consecutive integers is 270. what is the second number in the sequence

1 answer:

4 0

Alright, so if the first number is x, the second number is y, and the third number is z, we have x+y+z=270. Next, since we know that x=y-1 since it is less than y by one and z=y+1, we have y-1+y+y+1=y+y+y=3y=270. Dividing both sides by 3, we get y=90

the area of a rectangle is (y^2-8y+15) square inches. which expression represents a possible length? A. (y+5) B. (y-15) C. (y-2)

Pani-rosa [81]

D. (y-3)
I'm assuming that they want you to find the factors of the quadratic expression, which are (y-5)(y-3). (y-5) isn't up there, so (y-3) is the only solution that's really possible.

A rectangular exercise mat has a perimeter of 36 feet . The length mat is twice the width. Write and solve an equation to determ

Goshia [24]

ANSWER

72 square feet

EXPLANATION

The perimeter of a rectangle is given by:

P= 2l+2w

It was given that, the perimeter of the rectangular mat, is 36 feet.

36= 2l+2w

Divide through by 2.

$18 = l + w...(1)$

It was given also that, the length of the mat is twice its width.

This implies that,

$l = 2w ...(2)$

Put equation (2) into equation (1) to get,

$18 = 2w + w$

$18 = 3w$

$w = 6 \: ft$

This means that the length is 12 ft.

The area of the rectangular mat is

$A = l \times w$

$A = 6 \times 12 = 72 {ft}^{2}$

Answer:

Answer (e)

Step-by-step explanation:

Note that this graph has a zero at x = 1 and a vertical asymptote at x = -4. Only Answer (e) corresponds to that. Try letting x = 1. y is zero, correct? Try letting x = -4. y is undefined, correct?
