Answer: Tim weighs 90 lbs and his brother weighs 130 lbs
Answer:
-40x³ + 44x² - 66x - 36
Step-by-step explanation:
f(x) = 10x + 4
g(x) = -4x² + 6x – 9
Therefore:
f(x) · g(x) = (10x + 4) · (-4x² + 6x - 9) = -40x³ + 44x² - 66x - 36
Answer:
x=7
Step-by-step explanation:
1. ∠ADC is right angle, then
2. Angles ADB and BDC are complementary, then
3. You know that ∠BDC is 32° greater than ∠ ADB. Let then
Since you have that
This gives you:
