The answer to 15 is addition and multiplication
the answer to 16 is 0
x= r - h/y subtract r from both sides
x-r = -h/y multiply each side by -y
-y(x-r) = h
-xy +yr = h
So you just plug in the X value of the number that d represents for example if I plug in 2 for d
7(2)^2+10=38
Answer:
The answer is 2
Step-by-step explanation:
