Step-by-step explanation:
25x2−40x+18/
5x−3
Answer:
37
Step-by-step explanation:
There are 2 ways to do this, the first is to just count the number of shaded squares (35)
The second is to find the area of the larger shaded square and subtract the smaller un-shaded rectangles
The large square is 7x7=49 squares
There are two 2x3 rectangles, which are 6 each
49-6-6=37
Since you want to cancel x-terms, you're only concerned with the x-term coefficients, 5 and 4. You will want to use the opposite of one of these. It usually works well to multiply the equation with the least y-coefficient by the negative multiplier. That is ...
Multiply A by -4 and B by 5.
Y = -1/2x + 4
X + 2y = -8
Replace y in the second equation with the first one:
X + 2(-1/2x +4)=-8
Simplify:
X -X +8 = -8
Simplify:
8 = -8
Subtract 8 from both sides:
0 = -16
This is a false statement, so there are no solutions.
