Hey You!

The formula for area is length × width. So, let's try all of them:

9 × 8 = 72

9 × 9 = 81

9 × 10 = 90

9 × 11 = 99

Judging by all the possible lengths above, the only two answers that would provide an area either equal to 90 of greater than 90 are:

X=10 and X=10

Oh, I could help
You know the formula of area of rectangle
Aire= widthxlength
we have 9x8=72
9x9=81
10x9=90
and 11x9=99
So we have to choose the length 10 or 11

The perimeter of a rectangular field is 358 yards. If the length of the field is 95 yards, what is it’s width?
Andrej [43]

Answer:

84 yards (don't forget to label, as my friend failed a test because of it!)

Hope this helps

Step-by-step explanation:

The total perimeter of the field is 358

The are length and widths...

the length is 95

but since there are two lengths...

its 95*2 which is 190

358-190=168

Since there are two widths...

168/2= 84

Find the average rate of change for the function f(x) =x^2 -6x+2 on the closed side interval (-5,2)
s344n2d4d5 [400]

Answer:

- 9

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [a, b ] = [ - 5, 2 ], thus

f(b) = f(2) = 2² - 6(2) + 2 = 4 - 12 + 2 = - 6

f(a) = f(- 5) = (- 5)² - 6(- 5) + 2 = 25 + 30 + 2 = 57 , thus

average rate of change = \frac{-6-57}{2-(-5)} = \frac{-63}{7} = - 9
