Answer:
44 degrees
Step-by-step explanation:
if BAC and DAE are complementary then their sum is equal to 90 degrees
90 - 36 = 44 degrees
-x^2+7x-3=0 multiply the expression by -1
x^2-7x+3=0 we will complete the square so subtract 3 from both sides
x^2-7x=-3 now halve the linear coefficient, -7/2, square it 49/4, and add that to both sides...
x^2-7x+49/4=49/4-3 now the left side is a perfect square...
(x-7/2)^2=(49-12)/3
(x-7/2)^2=37/3 take the square root of both sides...
x-7/2=±√(37/3) now add 7/2 to both sides...
x=7/2±√(37/3)
Answer:
True
Step-by-step explanation:
Answer:
Step-by-step explanation:
45x = 9*5*x
81 = 9*9
GCF = 9
Take 9 out using distributive property { a*b - c*b = b*(a-b)}
45x - 81 = 9*5x - 9*9
= 9*(5x - 9)
=9(5x-9)
