Answer:
4x + 7y
Step-by-step explanation:
4(x+y) + 3y
Distribute
4x+ 4y+ 3y
add like terms
4x + 7y
A cube has 6 sides.
first calculate the area of 1 side and then multiply it by 6
the area for one side = S^2 ( or SxS)
15^2 = 15 x 15 = 225 square inches
now multiply that by 6:
225 x 6 = 1350 square inches total
the answer is B.
Answer:
1 + 2 a^n
Step-by-step explanation:
<u>Final Answer:</u>
x = 20
<u>Step-by-step explanation:</u>
we'll be using the pythagorean theorem method, in this triangle the missing letter is a.
formula: 
a = x
b = 21
c = 29
a = 
a = 
(note: 29² = 29 × 29 = 841 and 21² = 21 × 21 = 441)
a = 
a = 20
x = 20
