"a" is the answer because 3x+2 can not be equal to zero
Step-by-step explanation:
Answer:
The correct option in both cases is None of these
Step-by-step explanation:
(1.5x , 1.5y)
means we had (x,y) before
we only had to multiply each of the two by 1.5
So the percentage enlargement will be;
(1.5x-x)/x * 100
= 0.5x/x * 100
= 0.5 * 100 = 50%
The answer is none of these
for the second one, we have
(0.7x-x)/x * 100%
= -0.3x/x * 100%
= -30%
This is a 30% reduction
The answer here too is none of these
Answer:
B. 60cm^3
Step-by-step explanation:
The volume of a right triangular prism is
V = BH where B is the area of the triangle and H is height
B = 1/2 bh where b =5 and h =8
B = 1/2 *40 = 20
V = (20) * 3
V = 60 cm^3
We need to be careful to do the area of the triangle first
