Answer:
x^2+2x
Step by step explanation:
(2x^2+3x)-(x^2+x)
Remove unnecessary parentheses
2x^2+3x-(x^2+x)
When there is a - in front of an expression in parentheses, change the sign of each term of the expression and remove the parentheses
2x^2+3x-x^2+x
Collect like terms
x^2+3x-x
Answer:
<h2>120 square meters</h2>
Step-by-step explanation:
To find the SA of 2 Triangles, we will use the formula... B x H, and the Base and Height is going to be the dimensions of just 1 triangle, but it's going to give the answer for 2 triangles, in this shape, we have 2 triangles.
SA = B x H
= 6 x 4
= 24
24 square meters for both of the triangles
Now, let's find the SA of the rectangle on the bottom...
SA = L x W
= 6 x 6
= 36
36 square meters for 1 of the 3 rectangular parts, the one on the bottom
Now, lets find the SA of the 2 rectangles on the top. We'll use the dimensions of 1 rectangle and find the answer for 2 answers by using the formula...
SA = L x W x 2
= 6 x 5 x 2
= 30 x 2
= 60
60 square meters for the 2 rectangles on the top.
Now, we have to add all of our answers.
24 + 36 + 60 = 120 square meters
<h2>
Hence, the SA (surface area) of this shape is 120 square meters.</h2>

Answer:
f(g(x))= x-2
Step-by-step explanation:
f(g(x))= (x-4)+2 -plug g(x) into the place of x in the f(x) function
f(g(x))= x-4+2 -parentheses aren't needed
f(g(x))=x-2 -combine like terms
