what is the missing step in the given proof?
a.
statement: m∠4 = m∠15
reason: substitution property of equality
b.
statement: m∠4 + m∠8 = 180°
reason: definition of supplementary angles
c.
statement: m∠4 = m∠16
reason: transitive property of equality
d.
statement: ∠15 and ∠8 are supplementary.
reason: transitive property of equality

John used linear combination to solve the system of equations shown. he did so by multiplying the first equation by -3 and the second equation by another number to eliminate the x-terms. what number did jonas multiply the second equation by? 4x-6y=23x+5y=11

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.
