Answer:
+3
Step-by-step explanation:
if your subtracting a negitive it means your adding and its now a positive
Step-by-step explanation:
x+3x+90=360
4x=360-90
x=270/4
x=67.5
Answer:
395.5917959
Step-by-step explanation:
parallelogram area is 15 x 12
one half circle is 9^2
/2
the other is 7.5^2
/2
add all together
First find the value of X from the perimeter given
Perimeter = L*W
90 = 2 ((2x+2) + (x-2))
90 = 4x + 4 +4x - 4
90 = 8x
x = 11.25
Length = 2x + 2
2 (11.25) +2
=24.5
Width = x-2
11.25 -2
=9.25
h =x
= 11.25
Volume = L*W*H
24.5 * 9.25 * 11.25
2549.53 units^3
