You need to set this up with a proportion and solve. 18/x-5 = 13.5/12.
cross multiply 13.5x-67.5=216
now solve for x
13.5x=283.5
x=21
the missing side is equal to 21-5, which is equal to16
Answer:
a)
b)
c)
Step-by-step explanation:
We are given the following in the question:
1. Equivalent expression

Since all the terms are like terms, we can write,

2. Sum of given expression

3. Standard form of the expression

which is the required standard form of the given expression.
2 goes into all the terms so;
2(-2x² + 7x - 3) now you could factor it:
2(-2x - 1)(x + 3)
