8

Factor.

Mathematics
1 answer:
saul85 [17]3 years ago
4 0
The answer is B. (2x + 3)(4x - 1), because when you expand it you get 8x^2 + 10x - 3

2x × 4x = 8x^2
3 × 4x = 12x
2x × -1 = -2x
3 × -1 = -3

I hope this helps!

Somebody please help me out!
dmitriy555 [2]
Since the triangles are similar, all sides are proportional by the same scale factor.
The relationship between the bases 32 and 8 is 4 (32/8 = 4). This means that the smaller triangle need to be multiplied by a scale factor 4 to result in the bigger triangle.
This means that 4x + 12 is 4 times greater than 15.
The equation to solve for x can be written as:
4x + 12 = 4*15
Now just solve for x as u normally would
4x + 12 = 60
(Subtract twelve from both sides)
4x = 48
(Divide both sides by 4 to isolate x)
x = 12

I hope this somewhat helped :)
