which of the following represents the area of a rectangle whose length is 5x-3 and whose width is x+7​
Neko [114]

Answer:

The answer is 5x^2+32x-21

Step-by-step explanation:

To find the area of a rectangle, you have to multiply the length by the width. Then, you will get the equation of (5x-3)(x+7). Then, multiply these two together, therefore getting 5x^2+32x-21.

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is
Maksim231197 [3]
X + y = 24....multiply by -3
3x + 5y = 100
---------------
-3x - 3y = - 72 (result of multiplying by -3)
3x + 5y = 100
--------------add
2y = 28
y = 28/2
y = 14

x + y = 24
x + 14 = 24
x = 24 - 14
x = 10

solution is (10,14)...and x represents 3 point q's and y represents 5 point q's......so this tells me there are 10 three point q's and 14 five point q's.
