Answer: b = 2a/h
Step-by-step explanation:
a = bh/2
multiply each side by 2
2a = bh
divide each side by h
2a/h = b
1) a = 2, b= 3, c=2,
2) x^2 -2x-4 (a = 1, b=-2, c =-4)
3) x^2+x+3 (a,b = 1, c = 3)
4) 7x^2+8x-4 (a=7, b=8, c=-4)
Answer:
x=13
Step-by-step explanation:
I guess the angles are supplementary,Which means they have a sum of 180°.
11x - 15+5x-13=180
16x-28=180
16x=208
x=13
