Answer:
13 units^2
Step-by-step explanation:
one side of the square =



So area of square = Length * Length
=
*
= 13
Answer:
I believe the answer is, A.
Explanation:
Ordered pairs are classified as a function when none of the x’s in the ordered pairs match.
Like in b, a pair has 3.
And in c, two pairs have 1 and 3.
P=2 then 2^2+4=8
P=11 then 11^2+4=125
The square root of 2.25 is 1.5
There is a special kind of substitution which some books call it by comparison.
When the two equations are both
y=some function of x
y=some other function of x, then
we can substitute the second equation into the first giving
some function of x = some other function of x and start solving.
For example,
<span>y = –2x + 8
y = x – 1
substitute second into first
x-1=-2x+8
isolate x on left,
3x=9
x=3
second step is to substitute x=3 into second equation to get
y=x-1=3-1=2
Therefore the solution is (3,2)</span>
