25x2 + 16
25x2 − 64
25x2 + 64
Answer:
option (3) is correct.
Step-by-step explanation:
Given : factor 5x − 8
We have to choose an expression out of given option that is a difference of squares with a factor of 5x − 8
Using algebraic identity
a difference of squares is written mathematically as
Since one factor is 5x − 8
using identity stated above other factor has be 5x+8
Thus
On simplify , we get
Thus, option (3) is correct.

Answer:
a facilitator
Step-by-step explanation:
Michelle purchased 5 lbs of chocolates and 5 lbs of candy.
Let assume Michelle purchased x lbs of chocolates and y lbs of candy.
According to the given information,
Michelle spent a total of $40 on 20 lbs of candy.
So, the equation can be set up as:
Equation 1: 2.50x + 3.00y = 40
As, the totalweight of candy is 20 lbs, so we have:
Equation 2: x + y = 15
From equation 2: x = 15 - y
Substitute the value of x= 15 - y into Equation 2 as
2.5(15-y) + 3y = 40
37.5 - 2.5y + 3y= 40
0.5y = 2.5
y= 5
Substituting y= 5 into the second equation
x + 5 = 10
x = 10 -5
x = 5
Thus, 5 lbs of chocolates and 5 lbs of candy were bought.
