Answer:
25
Step-by-step explanation:
if the expression is + 10x + 25, then the binomial factors will be the same which is (x+5)(x+5).
Answer:
X= 1
Step-by-step explanation:
lets guess and check.
2, + the 2 her brother gives her is too high, its 4.
which means we go lower.
0 can't be right, because 0 + 2 = 2, not 3.
lets try 1.
1 + 2 = 3.
So that means X = 3.
Answer:
the answer is the first option
Answer:
Take away the 58 boxes from the 72 boxes and you will have 14 boxes left.
Then you have to multiply the 14 boxes left, by the 12 packs of pencils what gives you 168 packs of colouring pencils left.
The answer
the full question is
If A(x1, y1), B(x2, y2), C(x3, y3), and D(x4, y4) form two line segments, and AB ⊥ CD, which condition needs to be met to prove AB ⊥ <span>CD?
</span>
let be A(x1, y1)B(x2, y2) the first line, and C(x3, y3) D(x4, y4) the second
the slope of the first line is m = y2 -y1 / x2 - x1
the slope of the second line is m' = y4 -y3 / x4 - x3
so the condition needs to be met to prove AB ⊥ CD is
y2 -y1 y4 -y3
m x m' = --------- x ------------ = -1
x2 - x1 y4 -y3
