Answer:
Did you find the answer?
Step-by-step explanation:
Given:
The equation is:
Find-:
Binomials factor of the equation
Explanation-:
The quadratic equation,
Solve for factor
Then the factor is:
So, the factor is x + 4
Area of the big triangle (shaded area and small tris for below) is 36 * 51 divided by 2 (area of triangle is base * height over 2). this would give you 918.
area of the small triangle below is 51 * 11 divided by 2 (see above), which is 280.5.
shaded shape area is the big triangle shape minus the small triangle below, which is 918-270.5, which is 637.5 units.

2n + -7 + 3(4n + -3) = 0
Reorder the terms:
2n + -7 + 3(-3 + 4n) = 0
2n + -7 + (-3 * 3 + 4n * 3) = 0
2n + -7 + (-9 + 12n) = 0
Reorder the terms:
-7 + -9 + 2n + 12n = 0
Combine like terms: -7 + -9 = -16
-16 + 2n + 12n = 0
Combine like terms: 2n + 12n = 14n
-16 + 14n = 0
Solving
-16 + 14n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '16' to each side of the equation.
-16 + 16 + 14n = 0 + 16
Combine like terms: -16 + 16 = 0
0 + 14n = 0 + 16
14n = 0 + 16
Combine like terms: 0 + 16 = 16
14n = 16
Divide each side by '14'.
n = 1.142857143
Simplifying
n = 1.142857143</span>
