Use FOIL to multiply.
(3x - 7)(x + 5)
2 answers:
3x^2-7x+15x-35
=3x^2+8x-35
Answer:
3x²+8x-35
Step-by-step explanation:
<u>FOIL stands for:</u>
First -> (3x-7)(x+5)
Outer -> (3x-7)(x+5)
Inner -> (3x-7)(x+5)
Last -> (3x-7)(x+5)
Following FOIL, we get:
(3x-7)(x+5)
(3x)(x)+(3x)(5)+(-7)(x)+(-7)(5)
3x²+15x-7x-35
3x²+8x-35
Therefore, the expanded form is 3x²+8x-35

The solution is -0.609611 and -1.64, I do not think you can simply find this by factoring but the only way is graphing it
The angle in the triangle = 60 degrees
so tan 60 = h / (1/2) s = 2h /s
sqrt3 = 2h / s
h = sqrt3 s / 2
