Answer:
A. m and n both are positive is correct choice.
Step-by-step explanation:
We have been given that When factoring a trinomial of the form ax2 + bx + c where a, b, and c are all positive. That means:
a>0
b>0
c>0
Then ac>0 as product of same sign numbers is always positive.
Positive produce ac is possible only when both factors are of same sign.
In this situation, b>0 is possible only if both numbers are positive.
Hence choice A. m and n both are positive is correct choice.

3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using x as the denominator :
3x^3 + 5x (3x^3 + 5x) • x
3x^3 + 5x = ———————— = ——————————————
1 x
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
4.1 Pull out like factors :
+ 5x ![\frac{3x^3 + 5x}{1} = \frac{(3x^3 + 5x) [tex]3x^{3} + 5x = x • (3x^2 + 5)](https://tex.z-dn.net/?f=%5Cfrac%7B3x%5E3%20%2B%205x%7D%7B1%7D%20%20%3D%20%5Cfrac%7B%283x%5E3%20%2B%205x%29%20%5Btex%5D3x%5E%7B3%7D%20%20%2B%205x%20%3D%20x%20%E2%80%A2%20%283x%5E2%20%2B%205%29)

-1.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
a) Area of shape A= 17 (15z+1)
Area of A = 255z+17
b) Area of shape B
One way to find the solution is to take the area of
bigest rectangle ( z+z+8)*(z+4+6)
and subtract the two small rectangles
(z*(14-10)) and
(6*8)
Area of B= [(2z+8)(z+10)] -4z-48
=2z²+ 20z +8z +80 -4z-48 combine like terms
=2z² +24z +32
c) 225z+17 -2z² -24z -32 =
-2z²+201z -15
