Answer:
x^2+3x-5
Step-by-step explanation:
f(x) = 3x + 1
g(x) = x^2 - 6,
(f + g)(x)= 3x + 1 +x^2 - 6,
Combine like terms
= x^2+3x-5
Answer:
yes
Step-by-step explanation:
3.14
Answer:
B. $26.05
Step-by-step explanation:
Since this was a multiple choice question, I used process of elimination. I got rid of A because $13.95 - the ice cream ($13) would be no where near $43. For B, i did ($26.05) + ($26.05 - $13) which equals $39.10 and then i did ($39.10 + ($26.06 x 0.15) and that gave me $43 in all.
An acre is a surface measure, used in agriculture in several countries.
According to the country and the time, it is equivalent to several surfaces.
We will use the following conversion:
1 acre = 43560 feet ^ 2
Thus:
40 acre = 1,742,400 feet ^ 2
The area of the rectangle is:
1,742,400 = (1,200) * (x)
Clearing the other dimension we have:
x = (1742400) / (1200)
x = 1452 feet
Answer:
He needs 1452 feet of fence.
1. Find the area of the two sides (length x height) x 2 sides
2. Find the area of the adjacent sides (width x height) x 2 sides
3. Find the area of ends (length x width) x 2 ends
4. add the three areas together to find the surface area
