Answer:

Three times the difference of two times a number and five is equal to 24, what is x?

Step-by-step explanation:

To write any equation in word problems, it is important to identify all your parenthesis operations by their technical names. Subtraction is a difference. So since we are multiplying it by 3, it becomes three times a difference.

The answer would be b because if you substitute 5 in for x y=2x-6 would equal 4 and y=5x-21 would equal 4. I hope this helps!

Expand

Answer:

The working of expressions is shown below.

Step-by-step explanation:

We are given the following information:

a) Expand

$3(x+4)\\3\times x + 3\times 4\\3x + 12$

b) Expand and simplify

$4(x+5)-2(x-3)\\=(4x + 20) -(2x-6)\\=( 4x-2x) + (20 + 6)\\= 2x + 26\\=2(x +13)$

c) Expand

$(x+2)(x+7)\\=x\times x + x\times 7 + 2\times x + 2\times 7\\= x^2 + 7x + 2x + 14\\=x^2 + 9x +14$

d) Factorize fully

$12x-18\\=6(2x-3)$
