Answer:
-20
Step-by-step explanation:
when you solve: -7u-7=7, you get u= -2 and when you plug it in you get this equation 9(-2)-2=?
then you get -20
Answer:
Step-by-step explanation:
6! means 6×5×4×3×2×1
Answer:
5. x = 4+10
6.2 × x - 13
7.x = 7÷13
8. x-9 × 2
theres some. might be right. depends on teacher
As the picture highlights, the opposite sides have the same lengths. The perimeter is the sum of all lengths, so we have
Plug the required value for the perimeter and expand the right hand side:
Simplify the right hand side:
Add 36 to both sides:
Divide both sides by 12:
Now that we know the value for s, let's deduce the lengths of the sides:
We have to do BIMDAS
so starting with the brackets we do
35+27
which is 62
62÷4×12
then we work left to right for multiplication and division
62÷4
which is 15.5
then we finish with 15.5×12
which is 186
hope it helps.
