Answer:
40
Step-by-step explanation:
You would need 16 because 3 × 4 = 12 and you need to do the same to the blue so you would do the equation 4 × 4 = ? which is 16.
Ratio 1:5....added = 6
complimentary angles, when added, = 90 degrees
1/6(90) = 90/6 = 15
5/6(90) = 450/6 = 75
so ur 2 angles are : 15 and 75
One side is -4.
It can also be x + 4.
Turn 16 + 8x + x^2 into standard form —> x^2 + 8x + 16
Note: standard form is ax^2 + bx + c
Use the “foil” method to factor.
(x + 4)(x + 4)
x=-4
