Please help me

if don't know don't answer, if you answer i will report ​

A.) m = 1.5 | B.) p = -1 | C.) t = 2

Step-by-step explanation:

A.)

B.)

C.)

(a)=

4(m+3)=18

4m+12=18

4m=18-12

4m=6

m=

(b)=

-2(p+5)+8=0

-2p-10+8=0

-2p=0+10-8

-2p=2

p=

(c)=

3+5(t-1)=8

3+5t-5=8

5t=8-3+5

5t=10

t=

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
