The area of a rectangular wall of a barn is 75 75 square feet. its length is 10 10 feet longer than the width. find the length a

ziro4ka [17]

A = L * W
A = 75
L = W + 10

75 = W(W + 10)
75 = W^2 + 10W
W^2 + 10W - 75 = 0
(W + 15)(W - 5) = 0

W + 15 = 0
W = -15...not this one because it is negative

W - 5 = 0
W = 5 <=== width is 5 ft

L = W + 10
L = 5 + 10
L = 15 <=== length is 15 ft

Combine like terms to create an equivalent expression.

Juli2301 [7.4K]

<h2>Answer:</h2>

$\boxed{15.4z-12}$

<h2>Explanation:</h2>

Here we have the following expression:

$7.4z-5(-1.6z+2.4)$

We combine like terms in order to simplify expression. To do so, we combine terms with the same variable and exponents. In this exercise, let's apply distributive property first:

$7.4z-5(-1.6z)-5(2.4) \\ \\ Remember \ these \ rules: \\ \\ (+)(+)=+ \\ \\ (-)(-)=+ \\ \\ (-)(+)=+ \\ \\ (+)(-)=- \\ \\ \\ So: \\ \\ 7.4z+8z-12 \\ \\ \\ Combining \ like \ terms \ 7.4z \ and \ 8z: \\ \\ \boxed{15.4z-12}$

If y = 7x − 5, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

LenaWriter [7]

Given equation is y =7x - 5.

Let's plug in the values of x's to get their corresponding values of y's.

Let's plug in x = -5. So,

y = 7( -5) - 5 = -35 - 5 = -40

So, the first order pair is (-5, -40)

Hence, the first choice is not correct.

For x = 2, y = 7 (2) - 5 = 14 - 5 = 9.

Second order pair is (2, 9). So, second choice is also not correct.

Now for x = 0, y = 7(0) - 5 = - 5.

So, the third order pair is (0, -5).

Let's plug in x = -3 to check the third order pair list as we have already got two order pair (0, -5) and (2, 9) from that list.

For x = -3, y = 7(-3) - 5 = - 21 - 5 = -26.

Hence the correct choice is {(0, −5), (2, 9), (−3, −26)}.
