Substitute value of y from equation (1) in equation (2),
5x-4(5-3x) = -3
5x-20+12x = -3
17x=17
x = 1
Substitute it in equation (1),
y = 5-3(1)
y = 5-3 = 2
So, the values (x,y) = (1,2)
Area of the square = 6 * 6 = 36
area of 1 triangle = 1/2 x 6 * 4 = 12
area of 4 triangles = 4 * 12 = 48
total area = 36 +48 = 84 sq. cm
Answer:
(x-6)(2x+2)
Step-by-step explanation:
2x^2 + 2x - 12
by using splitting method
2x^2 - 12x + 2x -12
taking separate common from both pairs
2x(x - 6) + 2(x - 6)
(x - 6)(2x + 2)
Answer:
The cyclists should be riding 20 miles every day. (Which is a lot for me)
Step-by-step explanation:
All we have to do to find how many Miles per Day, is to divided the miles by the days.
120 ÷ 6 = 20
So, the cyclists should be riding 20 miles every day.
