Answer:
Step-by-step explanation:
As it is a second order equation, it means that it has two possible answers and they are
and
.
The famous quadratic formula for solving any second order equation is the following:

Where a is the coefficient of
, b is the coefficient of x, and c is the free term. In other words,

as the equation should be in the following form:

Therefore the possible answer should be the following,


by dividing the numerator and denominator by 2, we can deduce the following,
For your first answer 2=x+5/17 your second answer is 29. This is because "x" is the number that you need to bake which is 29. Therefore, 31/17=2
Answer:
Step-by-step explanation:
EF - base1
HG - base2
J-midpoint of EH
K-midpoint of FG
We are solving it by using formula:
JK=(base1+base2):2
25=(3x+2+7x-2):2
25*2=10x
50=10x
x=50:10
x=5
Good luck!
