Answer:
a. (5x+75)°
b. x = 21
c. X° = 21° and (4x+75)°= 159°
Step-by-step explanation:
A. Combine like integers.
B. (5x+75)°=180° Because they are suplementary angles.
5x°= 105°
5x ÷5 = 105 ÷ 5
x = 21
C. (4x + 75)°
4(21) + 75
84 + 75 = 159°
So
(x-4)^2=(x-4)(x-4)=x^2-4x-4x+16=x^2-8x+16
B = (d - c)/a
ab + c = d >> ab + c - c = d - c
ab = d - c >> (ab)/a = (d - c)/a
b = (d - c)/a
