Step-by-step explanation:
Area of triangle = 1/2 × the width × the length
42 = 1/2(x+3)(2x+8)
42 = 1/2×2×(x+3)(x+4)
42 = (x+3)(x+4)
(x+3)(x+4) = 42
x² + 7x + 12 = 42
x² + 7x + 12 - 42 = 0
x² + 7x - 30 = 0
(x-3)(x+10) = 0
x = 3, -10
x can't be -10 because the width and the length should be only + values
x = 3
Answer:
7x+5y +29= 0
Step-by-step explanation: first we have to find slop of the line that is.( Y2-Y1)/x2-x1
M = slope = 4+3)/-7+2
M= 7/-5
Equation of line y - y 1 = M (X - X1)
Y+3 = 7/-5 (x+2)
7x + 5y +29 =0 Ans .
X + x + x + 20 + 10 = 180
(combine like terms)
3x + 30 = 180
3x=180-30
3x=150
x=150/3
x=50
