2 answers:
Correct answer:
A) 0.5 x(x+2) =24 = 24
D) X^2 + 2x - 48 = 0
E) x^2 + (x+2)2 = 100
To check the rest unwrap the bracket
x^2+(x+2)^2=100
x^2+x^2+4+4x=100
2x^2+4x+4=100
2x^2+4x-96=0
Answer:
X=16ft
Step-by-step explanation:
area of right angled triangle = 1/2(base× perpendicular)
24ftsquare = 1/2 (X+2×X)
24×2ft square = 3X ft
48ftsquare = 3x ft
X = 48ftsquare÷ 3ft
therefore X = 16ft
