Answer:
(2x + 1)(3x + 2)
Step-by-step explanation:
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 6 × 2 = 12 and sum = 7
The factors are + 3 and + 4
Use these factors to split the x- term
= 6x² + 3x + 4x + 2 ( factor the first/second and third/fourth terms )
= 3x(2x + 1) + 2(2x + 1) ← factor out (2x + 1) from each term
= (2x + 1)(3x + 2) ← in factored form
Answer:
h = 13ft
Step-by-step explanation:
We can assume that the triangles are similar, so:
5 ft is to 26 ft as 2.5 ft is to h ft.
Which can be set up like this:
We can cross multiply:
5h = (2.5) (26)
5h = 65
h = 13ft
Answer:
first finish multiplying the signs that are out of the brackets
4-2+3-6
remember the BODMAS, addition comes first
4+5-6
9-6
