H(-2) = 2(-2)^2 - 3(-2)
= 2(4) - (-6)
= 8 + 6
= 14
Multiply the height by the base to get the area. 8 x 6 = 48. The area of the first triangle is 48 square inches. 8 x 10 = 80. The area of the second triangle is 80 square inches.
Answer:
The GCF/HCF is 9.
Step-by-step explanation:
27: 1,3,9,27
36: 1,2,3,4,9,12,18,36

Therefore the GCF/HCF = 9
I really hope this helps :)
It’s a square so it means you have to multiply 7*7*2.75 to get 134.75
Multiply that by 7.5 because one cubic foot holds 7.5 gallons
1010.625 *.03 since its 3 cents per gallon
30.318
Round up
$30.32 is the answer
