Are the heights and bases of the two triangles proportional? Explain. A : yes; The ratio of height to base for both triangles is 5/4.
B : yes; The ratio of height to base for both triangles is 4/5.
C : no ; the ratios of height to base are not equivalent.
D : no ; The triangles are not the same

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

yes
