Step-by-step explanation:
10 feet = 1 inch
50 feet = 5 inches
Do the same thing for the length.
If you don't under stand.
50/10 = 5
1/10 = x/50
10x = 50
x = 50/10
x = 5 inches
Then you do the same with the lenght.

Answer:
Step-by-step explanation:
i) 
Given,
y = -3x+1 (EQ1)
y = 2x-4 (EQ2)
Equate EQ1 and EQ2
EQ1 = EQ2
-3x+1 = 2x-4
-3x-2x = -4-1
x = 1
y = -3x+1
y = -3(1)+1
y = -3+1
y = -2
(1, -2)
~B
Step 2: She did not simplify under the square root correctly
under the square root:
(-6)^2 =36
and -4(5)(-8) =160
therefore under the square root it needs to be square root of 36+160 which is square root of 196.
That answer is 14 when square rooted
