$1.45
1.50 times .05= 0.075
the sales tax was 0.075 cents, so if you subtract that from $1.50, you get the price before sales tax
You multiply -4 to everything inside of the parenthesis which is 20w+12u-8
Because completementary angles add up to 180 degrees (angle 3 and angle 4)
and interior angles of a triangle will also add up to 180 degrees
if you compare these two facts, then angle 4 equals the 2 non adjacent interior angles
Answer:
see below
Step-by-step explanation:
Using the segment addition postulate
AB + BC = AC
x+2 + 7x-3 = AC
Combine like terms
8x -1 = AC
Using the segment addition postulate
PQ + QR = PR
8y+5 + QR = 13y+25
Subtract 8y from each side
5 + QR = 13y-8y+25
5 + QR = 5y+25
Subtract 5 from each side
QR = 5y+25-5
QR = 5y+20
The area is 288 units squared, or D. 72 times 4 equals 288.
