Answer:

Step-by-step explanation:
Given
See attachment for illustration
Required
Find x
To do this, we apply Pythagoras theorem.
From the attachment, the length of the hypotenuse is 16.7ft
While the length of the opposite/adjacent is 8.9ft
Length x is calculated using:



Take square roots


Answer:
(-3, 1)
Step-by-step explanation:
x-y=-4
3x-y=-10
------------
y=x-(-4)=x+4
3x-(x+4)=-10
3x-x-4=-10
2x-4=-10
2x=-10+4
2x=-6
x=-6/2
x=-3
-3-y=-4
y=-3-(-4)=-3+4=1
x=-3, y=1. (-3, 1).
7.
remember
(ab)/(cd)=(a/c)(b/d)
we can split them up
and
(x^m)/(x^n)=x^(m-n)

=

9.
2 to 3
4(x-1)=15
to
4x-1=15
the distribuutive prperty
a(b-c)=ab-ac
what he did was
a(b-c)=ab-c
he did not distribute the 4 to the -1
4(x-1)+3=18
minus 3
4(x-1)=15
distribute 4 to x and -1
4x-4=15
add 4 to both sides
4x=19
divide by 4
x=19/4
Answer:
Either the multiplictaion or division property of equality
