Answer:
a) x=-a, x=a+b
b) x=5/2a, x=1/3b
c) x=1/2a, x=a/a-2
Step-by-step explanation:
a) (x-a)(x-a)-b(x+a)=0
(x+a)(x-a-b)=0
x=-a, x=a+b
b) 3x(2x-5a)-b(2x-5a)=0
(2x-5a)(3x-b)=0
x=5/2a, x=1/3b
c) (2a-4)x^2=a^2(x-1)
(2x-a)(ax-2x-a)=0
X = 21
Y = 20

SR is congruent to ML
Answer:
0.40x = 320
Step-by-step explanation:
