-1x(6x - 8)
= -x(6x - 8)
= -x(6x) - x(-8)
= -6x^2 + 8x
By the Intersecting Secants Theorem we have
2x(2x+7)=x(x+23)
4x^2+14x=x^2+23x
3x^2=9x
3x=9
x=3
Since DY is length 2x,
the length of DY is 6.
Answer:
B is correct
Step-by-step explanation:
These are Absolute Value expressions. (How far from 0 on the number line) So disregard negative or positive signs. The only true statement would be 2<4.
Answer:
Step-by-step explanation:
We can write our unknown number like x
four less than the quotient of a number cubed and seven, increased by three

five times the difference of a number squared and six

nine more than the quotient of six and a number cubed, decreased by four

twice the difference of nine and a number squared
