Formula for perimeter of a rectangle = 2(L + W)
let the number be x
width = 2x + 8
length = 3(2x + 8)
substitute respectively
96 = 2 (2x + 8 + 3(2x + 8)) open the bracket
96 = 2 ( 2x + 8 + 6x + 24) collect like terms
96 = 2 (8x + 32) open the bracket
96 = 16x + 64
collect like terms
96 - 64 = 16x
32 = 16x
divide both sides by 16
32/16 = 16x/16
2 = x
therefore, the width = 2x + 8 = 2(2) + 8 = 4 + 8 = 12.
and the length = 3(2x + 8) = 6x + 24 = 6(2) + 24 = 12 + 24 = 36.
Answer:
A= -1,4 B=2,3 C=3,0 D=-1,-1
Step-by-step explanation:
idk what your looking for but I hope this helps
It means that x value is between 2 to 7 ( more than 2, but less than 7)
In notation, 2 < x < 7 or (2,7).
answer
congruent trapezoide for one
0,5(9+12)×1,5=15,75
area of picture frame =4×15,75=63
Answer:
Pretty sure its A and B
Step-by-step explanation:
Slope is -6/5, so that leaves just A B and E
Plugged it in, only A and B were correct
