Answer:
± 7
Step-by-step explanation:
Given
d = , then
d = 7 or - 7, that is ± 7
Since 7 × 7 = 49 and - 7 × - 7 = 49
7 is the square root of 49
we can find it by using lcm method
or
we know 7*7 is 49
so
49/7 - 7
therefore square root of 49 - 7
the equation would be f(x)= -9x+3 or y=-9x+3
132 square feet
a+b/2*h
20+24/2*6=132
here is what i found also you could of looked it up
(x,y)→(x+4,y)
35
