Answer:
(4x-5)(4x+5)
Step-by-step explanation:
16x^2 - 25
Rewriting
(4x)^2 - 5^2
We recognize that this is the difference of squares
a^2 - b^2 = (a-b) (a+b)
(4x)^2 - 5^2 = (4x-5)(4x+5)
Answer: 10/63
Step-by-step explanation: To multiply fractions, you just time's the top numbers and then the bottom numbers by themselves.
For instance: 2 x 5 = 10
9 x 7 = 63
and there is your answer.

Answer:
y = 2x + 3
Step-by-step explanation:
In the slope-intercept form of the equation of a line,
y = mx + b,
m = slope, and b = y-intercept.
Let's look at Adriana's equation and understand the parts:
y = 2x + 4
y = mx + b
m = slope = 2; b = y-intercept = 4
Now let's look at the description of Henry's equation.
He has the same slope as Adriana, so for Henry, m = 2 also.
His y-intercept is 1 less than Adriana's, so it is 1 less than 4. Henry's y-intercept is 3.
Now that we know that for Henry, m = 2, and b = 3, we can write his equation.
y = mx + b
y = 2x + 3
Answer: y = 2x + 3
The first one is the correct answer
