Answer:
x = 7.8
Step-by-step explanation:
2.6 + x = 10.4
-2.6 -2.6
x = 7.8
You do the inverse operations to find out x
D. some parallelograms are squares
First find the slope
which is y2-y1/x2-x1
= 3/5
and equation of line in point form is
y-5=3/5(x+3)
intercept from here we get 34/5
so equation in slope intercept form is
y= 3/5x+34/5
6a² + 7ax - 3x²
6a² + 9ax - 2ax - 3x²
3a(2a) + 3a(3x) - x(2a) - x(3x)
3a(2a + 3x) - x(2a + 3x)
(3a - x)(2a + 3x)
