Do 12-5 then 6.4 then 2.2 then whatever answer you get for 12-5 multiply it by the answer you get for 6.4 then subtract whatever answer you get for 2.2 hope this helps!
Answer:
Step-by-step explanation:
f(x)=4x²+19
f(-5) = 4(-5)² + 19 = 4*25 + 19
= 100 + 19 = 119
Since vertical angles are congruent, (4x+7)=5(x-4). So simplifying we get 4x+7=5x-20. If we add 20 on both sides we get 4x+27=5x. Now when we subtract x from both sides, we get x=27
32 / (14 2/9) =
32 / (128/9) =
32 * 9 / 128 =
288 / 128 =
