Answer:
see explanation
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent.
Thus ∠D = ∠A and substituting values
2x = x + 31 ( subtract x from both sides )
x = 31
Hence
∠A = x + 31 = 31 + 31 = 62
∠D = 2x = 2 × 31 = 62
Answer:
p = -2
Step-by-step explanation:
O we have to solve this equation:
24p + 12 - 18p = 10 + 2p - 6
First, we will operate what we have in both sides:
24p - 18p + 12 = 10 - 6 + 2p
6p + 12 = 4 + 2p
We substract 2p in both sides and 12 too.
6p + 12 - 2p - 12 = 4 + 2p - 2p - 12
4p = -8
Now, we divide both sides by 4
4p/4 = -8/4
Answer:
38
Step-by-step explanation:
32 minus 3x4 which is 12
and you get 20
add 18
and you get 38
Im assuming the base of the triangle is 4cm. The volume is

.
If the dimensions are tripled, the base is 12, the height is 24, and the length is 18. The volume is

, which is 27 times bigger.
If you are increasing each side by a factor of x, you are multiplying the original by
