Area of a trapezoid is 
Answer:
Step-by-step explanation:
Given:
Number line is from range -2 to 2 with all increment of ±
on both sides.
Step 1: First we will solve the equation we will get;
Step 2: Now we will try to make the denominator common so we will get;
Step 3: Now from the number line when we subtract 
from 
we get number of spaces left are - 7
Hence now it will become:
Hence the final Answer is
Answer:
she worked 9 hours at sporting goods store and 6 hours on piano lessons.
Step-by-step explanation:
total hours=15
8.47x + 17(15-x) = 178.23
8.47x + 225 - 17x = 178.23
225 - 178.23 = 17x - 8.47x
76.77 = 8.53x
x = 76.77 / 8.53
x = 9
therefore she worked 9 hours at sporting goods centre and the remaining hours (15-9) giving piano lessons.
You seem to already see that you need to multiple x with the other numbers. When you start off solving it you'd get.. x-6=x2(to the power of) + 6x . Then just move the equation over from the left to the right. and solve, I've got -6+x2(power of 2)+7x, that's it
