Answer:
(x-1)(x+5)=0
x=1; x=-5
Step-by-step explanation:
x²+4x=5
x²+4x+2²=5+2²
(x+2)²=3²
(x+2)²-3²=0
(x+2-3)(x+2+3)=0
(x-1)(x+5)=0
(x-1)=0 ; x=1
(x+5)=0; x= - 5
Answer:
11 ; 13
Step-by-step explanation:
Let the numbers be :
x and x + 2
x * (x + 2) = 6(x + x + 2) - 1
x² + 2x = 6(2x + 2) - 1
x² + 2x = 12x + 12 - 1
x² + 2x = 12x + 11
x² + 2x - 12x - 11 = 0
x² - 10x + 11 = 0
x² - 11x + x + 11 = 0
x(x - 11) + 1(x - 11) = 0
(x - 11) = 0 or (x + 1) = 0
x = 11 or x = - 1
X cannot be negative
x = 11
x + 2 = 11 +2 = 13
By definition, BF = 1/2 * CE;
So, BF = 1/2 * 90 = 45.
BF = 45
