The length of the side is 7 because you have to multiply the length and the width together to get the area. 7x7=49
.88y +.03y = final cost or more simply .91y = final cost
100% - 12% discount leaves 88% of y (.88y)
3% tax = .03y
.88y + .03y = .91y
Answer:
80
Step-by-step explanation:
The three angles of a triangle add to 180 degrees. One angle is 10, the second is a right angle( which is 90 degrees). Let the third angle be x
10 +90 +x = 180
Combine like terms
100 +x =180
Subtract 100 from each side
100-100 +x= 180-100
x = 80
