There is not enough information given in what you have said to find the number of tiles. We need either the area or dimensions of the kitchen to find the information you are looking for.
1 -since everything includes 4a, we can factor that to get 4a(a-4b^3+2b^2c)
2 - since 5 and 3 add to 8 and multiply to 15, we can do (n+5)(n+3)
3 - since -5 and -4 add to -9 and multiply to 20, we can do (g-5)(g-4)
4 - since -10 and 3 add to -7 and multiply to 30, we can do (z-10)(z+3)
5 - we can factor out 4y to get 4y(y^2-9).
I got the numbers in 2, 3, and 4 with a guesstimating and checking approach
Answer:
the answer is y=−3x5−35y=-3x5-35
y=−2x+5y=-2x+5
hope this helps :)
If the equation is arranged in point-slope form we get:
y = 2x - 11.
The y-intercept is at (0, -11).
Therefore a point on the line is (0, -11).
