Answer:
B (5/8 - 6/8)
Step-by-step explanation:
Since we can just multiply the second fraction by two to get a similar denominator, we just need to multiply the second fraction.
2y - 5(y -3)
Use the distributive property.
2y - 5y + 15
Combine like terms of 2y and -5y. 2 - 5 is -3.
-3y + 15
None of these are accurate. Are you sure you’re including the entire question?
Given polynomial 
.
(a) To show that (x – 3) is a factor of f(x).
Factor theorem:
<em>A polynomial f(x) has a factor of (x – a), if and only if f(a) = 0.</em>
= 0
f(3) = 0
Hence (x – 3) is a factor of f(x).
(b) 
Here 
is common in first 2 terms and 2 is common in next 2 terms.
Now, (x – 3) is common in both terms.
and 
x = 3 and 
3 is the real root.
using quadratic formula solve and find the other roots.
These are complex roots.
Hence 3 is the only real root of the equation f(x) = 0.
Answer:
180 square inches
Step-by-step explanation:
First off since the square will be easiest to do
a=a^2
a=6^2
a=36
now for the triangles
a= height of triangle * base/ 2
a= 12*6/2
a= 36
and since there is 4 of the triangles we multiply 36 by 4
=144
now we add 144 to 36 and we have the total
