Answer:
16s^2 -9
Step-by-step explanation:
(4s+3)(4s–3)
FOIL
first : 4x*4x = 16s^2
outer -3 *4s = -12s
inner 3*4s = 12s
last = 3* -3 = -9
Add them together
16s^2 -12s+12s -9
Combine like terms
16s^2 -9
multiply and add then subtract. steps are in the picture.
Twelve and nine thousandths
7(6+2) = 7(8)=56
The answer is:
7(6)=42 + 14=56
So -56 -13 = -69
So the answer would be 69?
