I do not fully understand your question but I will still try to answer it. One cubed may look like this: 1³. Two: 2³. and Three: 3³. Written in an expression may be a bit difficult, but I may try. 1³- 2³ + 3³ = X. I hoped I helped in a way!
Answer:
(x,y) = (-2,7)
Step-by-step explanation:
7x+2y=0
9x+4y=10
y = -9x/4 + 5/2
7x+2 (-9x/4 + 5/2) = 0
5x/2 = -5
5x = -10
x = -2
use x and substitute to get y
y = -(9/4) (-2) +5/2 = 7
It equals to:
(3(a+h)^2 - 3a^2) / h = 3(2ah+h^2) / h = 6a + 3h
Angle 1 + angle 6 is equal to 180° because they are on the same line.
so if angle 6 is 125° so angle 1 is:
180 - 125 = 55° :)))
i hope this is helpful
have a nice day
