3/7 = 9/x
cross multiply because thats how u solve proportions
(3)(x) = (7)(9)
3x = 63
x = 63/3
x = 21
and if u will notice : 3/7 and 9/21 ....9/21 reduces to 3/7....so these are equivalent fractions...because proportions are nothing but equivalent fractions
I Think The Answer Is -20 Or 66...Because When I Wrote It Out On Paper I Tried To Solve For Me & I Came Up With 66 But When I Wrote It Out Once More I Came Up With -20..Hope I Helped.
A. W = L - 10
b. P = 2(L + L - 10)
P = 2(2L - 10)
P = 4L - 20
c. solve
P = 4L - 20
244 = 4L - 20
244 + 20 = 4L
264 = 4L
264 / 4 = L
66 = L or L = 66
Length of the rectangle = 66 mm
d.
W = L - 10
W = 66 - 10
W = 56
Width of rectangle = 56 mm
X^2-4 = x^2 - 2^2
= (x+2)(x-2)
Answer:
<u>option C. (x + 4) and (x − 8)</u>
Step-by-step explanation:
A factor is one of the linear expressions of a single-variable of the polynomial.
Given: y = (1/4)(x + 4)(x - 8)
When y = 0
∴ (1/4)(x + 4)(x - 8) = 0 ⇒ multiply both sides by 4
∴ (x + 4)(x - 8) = 0
So, the factors of the function are (x+4) and (x-8)
The answer is option <u>C. (x + 4) and (x − 8)</u>
