If you are solving for y, your answer is -1.
First, x=4 so plug in the 4 in every into every x.
Second, 4^2 is 16. 8(4) is 32.
Third, 16 - 32 + 15= -1
Answer:
(B) 18 cm x 8 cm
Step-by-step explanation:
let the length be x,
then the width is 
x + 2
2( x + 2 + x ) = 52
x + 2 + x = 26
= 24
x = (24*3)/4
x = 18
then the length is 18 cm
and width is (1/3)*18 + 2 = 8
Therefore the dimensions are length:width = 18 cm : 8 cm
A 1 = 57, a 2 = 61, a 3 = 65 ( arithmetic sequence )
a n = a 1 + ( n - 1 ) d
a 2 = a 1 + d
61 = 57 + d
d = 61 - 57
d = 4
a 9 = 57 + 8 * 4 = 57 + 36 = 93
Answer: Her score on the 9th assessment will be 93 points.
L(which is length) is equal to 42 divided by width which is 6. so the equation is L=42/6
