Answer:
a² + 2ah + 3a + 3h + 5 + h²
Step-by-step explanation:
to evaluate f(a + h) substitute x = a + h into f(x)
f(a + h)
= (a + h)² + 3(a + h) + 5 ← distribute
= a² + 2ah + h² + 3a + 3h + 5
The answer is 5a pretty sure
Answer:
x = 80
Step-by-step explanation:
Let x be the unknown number
1/2 x - 10 = 30
Add 10 to each side
1/2x -10+10 = 30+10
1/2x = 40
Multiply each side by 2
1/2x * 2 = 40*2
x = 80
Median:(13+43)/2 so it is 28
The mean:(11+13+43+47)/4 = 28.5
There are 2 senators from each of the 50 states.
All senators are present, therefore there are 100 senators.
48 senators voted in favor of a treaty.
Let x = the number of additional senators who should vote in favor of the treaty to achieve 2/3 of 100.
That is,
48 + x ≥ (2/3)100
x ≥ 200/3 - 48
x ≥ 18.667
x should be an integer, therefore
x ≥ 19
Answer: 19 or greater
