Tyler is simplifying the expression 6−2x+5+4x.
Here is his work:
6−2x+5+4x
(6−2)x+(5+4)x
4x+9x
13x
His work is incorrect. Explain the error he made.
3.
Simplify the expression 6−2x+5+4x. Hint: Your final expression shoul donly have two terms.
4.
Factor to write an equivalent expression:
36a−16
5.
Expand to write an equivalent expression:
−14(−8x+12y)

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
