Answer:
Answer is y^2-81
Step-by-step explanation:
C
According to formula
(a+b)(a-b)=a²-b²
So
(y+9)(y-9)
=y²-(9)²
=y²-81
ANSWER: ADC=82
bda = 144
(7x+34)+(9x+46)=144
16x+80=144
16x=64
x=4
9(4)+46=82
adc=82
The Slope of f(x) = –7x + 9 is (-7)
The slope of h(x) = –5(–7x + 9) is (35)
The y-int of h(x) is (-45).
8y
Product means multiply
8*y
