Answer:
d^2 +2d-8=0
first pick two numbers which add up to make +2 and by multiplying those two numbers they should be able to create -8.
so for example 4 and 2
4-2=2
4 x -2= -8
so now factorise:
d^2 +2d-8=0
d^2+4d-2d -8=0
d(d+4)-2(d+4)=0
d+4=0 d-2=0
d=-4 d=2
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
(6)² = 3x
then x= 36/3
x= 12
To simplify this expression would be 4x-3
It's called a decimal.
I hope it helps.
Wait is it not at all 14.5 or 14 1/2 Because with the math I did I got 14 1/2
