Answer:
cubic
Step-by-step explanation:
you can eliminate all of the other ones
Answer:
0
Step-by-step explanation:
Make and equation and solve for x.
(2x+10)^2 = 4(x-5)^2 Now the easiest thing to do is use the formula for squared binomial, (a+b)^2 = a^2 + 2ab + b^2.
4x^2 + 40x + 100 = 4(x^2 - 10x + 25)
4x^2 + 40x + 100 = 4x^2 - 40x + 100
From hear you can cancel out similar terms
40x + 100 = - 40x + 100
40x = -40x
add 40x to both sides
80x = 0
x = 0
The only solution to this is 0.
Answer: 21n + 70= 21n plus 70
Step-by-step explanation:
step by step explanation the n is 21 plus 70 plus then you have to do equals on the sign 21n in the box where it says n add 21 then add 70 and then add a = sign and your done
y - y1 = m(x + x1)
m = (y2 - y1)/(x2 - x1) = (-6 - 2)/(-1 - 5) = -8/(-6) = 4/3
y - 2 = 4/3(x - 5) is a possible answer
y + 6 = 4/3(x + 1) is also a possible answer
