Area=LW
<span>10x^2-29x-21=area
factor and those are the lengh and width
(2x-7)(5x+3)
perimiter=2(L+W)
P=2(2x-7+5x+3)
P=2(7x-4)
P=14x-8
answer is D

42 divided by 40 = 1.05 = 105%. Hope I helped!
Answer:
A
Step-by-step explanation:
A linear term a variable to the power of one. but there is none of those so theres is no linear term. A quadratic term is a variable to the power of 2, there is one of those so our quadratic term is x^2. A constant term is a term with no variable, thats -7. Our answer is A.
Answer:
x = ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
Step-by-step explanation:
Given
= ![\frac{x}{x+2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Bx%2B2%7D)
multiply numerator/ denominator of
by 4, thus
= ![\frac{4x}{4(x+2)}](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B4%28x%2B2%29%7D)
Since the denominators are common , equate the numerators, that is
4x = 3 ( divide both sides by 4 )
x = ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
2838=total
Women = 3X +5
Men = 4(3x+5)-3
Children= x
Men= 12x+17
Total= 16X +23
16x + 23 = 2838
16x = 2815
X = 2815/16
