Answer: Length = 36m
Step-by-step explanation:
P = w * 2 + l * 2
Width = w
Length = w + 5
P = w + w + (w + 5) + (w + 5)
P = 4w + 10
134 = 4w + 10
-10
124 = 4w
/4
31 = w
So, the width is 31m.
Length = 31 + 5
31 + 5 = 36
Therefore, the length is 36m
You can also check this: P = w * 2 + l * 2
31 * 2 = 62
36 * 2 = 72
72 + 62 = 134
Answer: x= -4
Step-by-step explanation:
6x+9= -15
-9. -9
6x= -24
X= -4
25x^2 - 16 =
(5x + 4)(5x - 4) <==
Answer:
-39
Step-by-step explanation:
Substitute x by - 3 and y by 4
(-3)^3 - 3 *4 = - 39
