n²-25
Explanation:Expand the polynomial using the FOIL method. (A handy way to remember how to multiply two binomials. It stands for "First, Outer, Inner, Last")
Answer:
n² - 25
Step-by-step explanation:
(n - 5)(n + 5)
Each term in the second factor is multiplied by each term in the first factor, that is
n(n + 5) - 5(n + 5) ← distribute parenthesis
= n² + 5n - 5n - 25 ← collect like terms
= n² - 25
the function A(t)=728(1 + 0.04)t represents the amount of money in the account after t years. How much money did Adtia originally invest?
Answer:
$728.00
Step-by-step explanation:
$728.00 I’m assuming. Because the equation should be A(t)= P(1+i) ^t right? Telling us that P= principal, i= interest & t= time.
I’m assuming from MY financial mathematics class.

Please solve for X and find the measure of A.
Answer:
x = 18°
m∠A = 110°
Step-by-step explanation:
Hello!
Angle A and Angle B are supplementary. Supplementary means they add up to 180°.
Step 1: Solve for x
We can add the two angles together and make it equal to 180° because they are supplementary.
Angle A + Angle B = 180°5x + 20° + 9x - 92° = 180°14x - 72° = 180°14x = 252°x = 18°x = 18°
Step 2: Solve for Angle A
Now that we know the value of x, we can plug it in for the equation of Angle A and solve for the measure of Angle A
Angle A = 5x + 20°Angle A = 5(18°) + 20°Angle A = 90° + 20°Angle A = 110°Angle A = 110°

45. A square has the same perimeter as a 5 x 11 rectangle. What is the area of the
square?
Answer:
The area of the square is = 64
Step-by-step explanation:
The perimeter of rectangle = Perimeter of the square
The rectangle has a length (l) of 11 and a width (w) of 5.
The perimeter of a rectangle = 2·l×2·w = 2×11+2×5 = 32
The perimeter of a square = 4·s => Since the perimeter of the rectangle = the perimeter of the square we can find out the side of the square by using the formula in bold.
The perimeter of the square = 4·s = 32
s = [tex]\frac{32}{4}[/tex] = 8
The area of a square is = s×s = s²
The area of the square is = s² = 8² = 64
Why is it helpful to represent fractions and division with models? (pls make answer pretty long, thanks :)
Answer:
Whether you're teaching the meaning of fractions or fraction operations, visual models can help students connect fractions to what they already know. Division is an essential foundation for fractions. Once students can divide objects into equal groups, they can begin to grasp dividing a whole into equal parts.
Step-by-step explanation:
Models can help students better understand what they are working with!

Bailey writes the expression g2 14g 40 to represent the area of a planned school garden in square feet. What factors can be used to find the dimensions of her garden?.
The dimension of her garden whose area is g² + 14g + 40 is (g + 10) and (g + 4).
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
Bailey writes the expression g² + 14g + 40
g² + 14g + 40
g² + 10g + 4g + 40
g (g + 10) + 4 (g + 10)
(g + 10)(g + 4)
The dimension of the factor is (g + 10) and (g + 4).

What are the y-intercept and the horizontal asymptote of g(x) = 3x + 4?
The coefficient of the variable will be the horizontal asymptote . Hence the horizontal asymptote will be 3
How to calculate the y-intercept and horizontal asympototesGiven the function g(x) = 3x + 4
The y-intercept is the point where x = 0
g(0) = 3(0) + 4
g(0) = 0 + 4
g(0) = 4
Hence the y-intercept is at (0, 4)
For the horizontal asymptote of g(x) = 3x + 4
The coefficiet of the variable will be the horizontal asymptote . Hence the horizontal asymptote will be 3
