(2a+4b)(2a-7b)=
2a(2a-7b)+4b(2a-7b)=
4a^2-14ab+8ab-28b^2=
4a^2-6ab-28b^2
Answer:
We know that the angle which lineer and divided by |AB| equal to 130°
Step-by-step explanation:
if 130° look at the 2x+260 we can say that 2x+260=260° so X equal to Zero (0)
Answer:
with (-11, 1) as the vertex
Step-by-step explanation:
The vertex form of a parabola is given by
y = a (x-h) ^2 +k
where (h,k) is the vertex
h(x) = -(x + 11)^2 +1
is written in vertex form
h(x) = -(x - -11)^2 +1
with (-11, 1) as the vertex
First divide 6,513 by 10.
Second look at the place value the 5 is in.
The 5 represents the tens place or 50.
I hoped this helped!
