Answer:
48 cm
Step-by-step explanation:
If it's square and the area is 144, then the sides are each 12cm (a = l x w, 144 = 12 x 12)
12cm x 4 sides = 48cm
I think it is 8. im not sure
Answer:
x = -4
Step-by-step explanation:
Distribute:
-2(x + 5) = -2
-2(x) -2(5) = -2
Multiply:
-2(x) -2(5) = -2
-2x - 10 = -2
Add 10 on both sides:
-2x - 10 = -2
+10 +10
-2x = 8
Divide by -2 on both sides:
-2x = 8
/-2 /-2
x = -4
answer:
the answer is -3 and 8
Step-by-step explanation:
we will place -3 in the equation
(x+3)(x-x)=0
(-3+3)=0 (because -3+3 will cut down together)
we will place two 8(eights) in the equation
(8-8)=0
final answer is
(0)(0)=0
so -3 and 8 fits well in the equation
so it is 87.5 so what you do do is 25 x 3.50 and it will give you 87.5
