So 5x=30
then x= 30/5
and x=6
so the answer is last one !
Answer:
2R^2 + 21R - 36
Explanation:
To answer this question, we will follow these steps:
1- expand the brackets
2- gather like terms
Steps are as follows:
(2R-3)(R+12) = 2R(R) + 2R(12) - 3(R) - 3(12)
= 2R^2 + 24R - 3R - 36
= 2R^2 + 21R - 36
Hope this helps :)
Answer:
a) 
b) 
Step-by-step explanation:
a) Let the required polynomial be p(x).
We have the relation, 
+ p(x) = 18
i.e. p(x) = 18
i.e. p(x) =
b) Let the required polynomial be q(x).
We have the relation, + q(x) = 0
i.e. q(x) = 0
i.e. q(x) =
The way you find area is multiplying width times height, so you have to multiply 15 by 4 which equals 60. Therefore the answer is 60
