Find f(g(x))
This is calculated as:

Substitute g(x) for x

Substitute 

Open bracket

The answer to the first problem is G.
Since there are 3 boys and 9 girls who are left-handed, that makes 12 people in total in sixth grade who are left-handed. The total number of sixth graders at the middle school is 150 since there are 90 girls and 60 boys in that grade. Divide 150 from 12 to get 0.08. You change it to percentage form by multiplying 0.08 by 100 to get 8%.
The answer for the second problem is C. You change the percentage (in this case it is 76%) to decimal form by dividing by 100 to get 0.76. You then multiply 0.76 with 8,950 to get 6,802.
Y=2x+5
4x-2y=-10
4x-2(2x+5)=-10
4x-4x-10=-10
-10=-10
Answer:
89 square cm
Step-by-step explanation:
The shape has two rectangles and two triangles. The triangles are at the edges and for the area for triangle we get by 0.bh where b is base and h is heigjt. Since the triangles are same then the above formula is multiplied by 2 hence area is 0.5bh*2=bh. Here b is 4cm and h is 3 cm then are is 
Area of rectangle is given by lw where l is length and w is width
For the rectangle at the bottom, the area is 
For the rectangle on side, the area is 
Total area is 12+44+33=89 square cm
