Number one: Just plot down on the number like the numbers you have. Just took the test for this.
Answer:
a = 6
Step-by-step explanation:
Given
+ 4 = 6 ( subtract 4 from both sides )
= 2 ( multiply both sides by 3 to clear the fraction )
a = 6
The answer should be (2)
[line 3] should be 3x+12=18 instead of 3x+4=18

Answer:
b2 = 2A/h -b1
Step-by-step explanation:
The usual formula for the area of a trapezoid is ...
We can solve this for b2:
1.10*2*(7.5*2 + 10*(7.5+2)) = 242 . . . . square inches
The total area is 2(LW +H(L +W)). You want 10% more than that, so can find it by multiplying the area by 1.10.
