A=10x(15x)-p(4x)^2
A=150x^2-16px^2
A=(150-16p)x^2
Answer:
Sure! I'll look you up!
Step-by-step explanation:
Answer:16
Step-by-step explanation:
4x - 2y - z = - 5 ______×2x - 3y + 2z = 3 _______×13x + y - 2z = - 5 ______×1
8x - 4y - 2z = - 10x - 3y + 2z = 33x + y - 2z = - 5
8x - 4y - 2z = - 10(+) x - 3y + 2z = 3_____________9x - 7y = - 77y = 9x + 7y = 9/7x + 1
x - 3y + 2z = 3(+) 3x + y - 2z = - 5_____________4x - 2y = - 24x - 2(9/7x + 1) = - 24x - 18/7x - 2 = - 210/7x = 0x = 0
y = 9/7(0) + 1y = 1
0 - 3(1) + 2z = 32z = 6z = 3
Answer:
1. x=55 2. x=12
Step-by-step explanation:
1. 3x-60=x+50
2x=110
x=55
2. 8x-34=5x+2
3x=36
x=12
