Answer:
. so, suppose for (x-9)squared. = x*2 + 81 - 2 {1} {9x} = x*2 + 81 -18x. that's the answer.
Step-by-step explanation:
the formula is (a - b) squared. = a*2 + b*2 - 2ab.
C. 75 im pretty sure all i know is that is one of the postitive ones it might be D
Answer:
144.75in^2
Step-by-step explanation:
V=bh/3
so..
V=(18.4)(23.6)/3
V=434.24/3
V=144.74666
round to the nearest tent
V=144.75 inches
X= 60 and y = 120
As we can tell x and y add up to 180 as angles on a line are equal to 180 and we know the value of x as angles in a triangle add up to 180
Answer:
multiply first equation by 2 in order to have same amount of x in both equations
2x-4y=6 now subtract equations
y=3 thus x=9
