Answer:

Step-by-step explanation:

Because when you want to find the erea of something you mutiply the width and length

length=long

with=wide

7 meters long, length × 8 meters wide,with

length×with

7×8=

=56

PLEASE HELP

Answer:

The answer to your question is letter B

Step-by-step explanation:

Process

1.- Find two points of each line

Line A (-2, 0) (-1, 2)

Line B (-1. - 5) (-6, 0)

2.- Find the slope and equation of each line

Line A

$m = \frac{2 - 0}{-1 + 2}$

$m = \frac{2}{1}$

m = 2

y - 0 = 2(x + 2)

y = 2x + 4

Line B

$m = \frac{0 + 5}{-6 + 1}$

$m = \frac{5}{-5}$

m = -1

y - 0 = -1(x + 6)

y = -x - 6

3.- Find the inequalities

Line A, we are interesteed in the lower area of the line, so the inequality is

y ≤ 2x + 4

Line B, we are also interested in the lower area of the line so the inequality is

y ≥ - x - 6

A rectangular corral is enclosed using 120 m of fencing. The corral uses the side of a barn as one of its sides, so fencing is r

Yuliya22 [10]

The dimensions would be 40 m by 40 m.

To maximize area and minimize perimeter we make the dimensions as close to equal as possible. Since we only need fencing on 3 sides, 120/3 = 40; we can use 40 for each side.

C= m over 3 π d to the second power , for m

julia-pushkina [17]

Solve for m:C = 1/3 π d^2 m
C = 1/3 d^2 m π is equivalent to 1/3 d^2 m π = C:1/3 π d^2 m = C
Divide both sides by (π d^2)/3:Answer: m = (3 C)/(π d^2)

Question 11 (5 points)

Semenov [28]

Hello :)

here you need to use the slope intercept formula to find your equation:

y= mx+b

b= the y- intercept

m= the slope

we are already given the slope and the x & y

y=-3x+(-2)

your answer would be a) y = -3x - 2
