First replace y with 15.
1/5x-10=30
Then just solve from there.
x=200
Answer:
A = 5x³ + 17x² - 35x - 30
Step-by-step explanation:
the shaded area (A) is calculated as
A = outer area - inner area
= (5x + 3)(x² + 4x - 10) - 3x(2x - 1) ← distribute parenthesis
= 5x³ + 20x² - 50x + 3x² + 12x - 30 - (6x² - 3x)
= 5x³ + 23x² - 38x - 30 - 6x² + 3x ← collect like terms
= 5x³ + 17x² - 35x - 30
Answer:
a = -8
Step-by-step explanation:
-48 = 6(a)
divide both sides by 6
-8 = a
Answer:
It would last for 3.2 days.
Step-by-step explanation:
100 men = 8 days
10 men = 0.8 days
60 men = 0.8 x 6 = 4.8 days
Now you subtract the days of 100 men and 60 men
8 - 4.8 = 3.2 days
Hope this helps!
Answer:
b
Step-by-step explanation:
x = 2 in this situation, so plug in 2 for x.
f(2) = (x + 1)2
f(2) = (2 + 1)2
f(2) = (3)2
f(2) = 6
f(2) = 6. That means b is the answer.
