Answer:

2(x^2-16y^2)

Step-by-step explanation:

9514 1404 393

Answer:

  2(x -4y)(x +4y)

Step-by-step explanation:

Once you factor out the common factor of 2, what remains is the difference of squares. That can be factored further.

The factoring of the difference of squares is ...

  a² -b² = (a -b)(a +b)

Then we have ...

  2x² -32y² = 2(x² -16y²) = 2(x² -(4y)²)

  = 2(x -4y)(x +4y)

Answer: 23.4 ft^3

Step-by-step explanation: The perimeter of the base is 10.7, it is a square so the 4 sides of the base are equal. One side of the base is equal to 2.675 if the perimeter (4 sides) is equal to 10.7, so plug that and the height into the formula for the volume of a square pyramid to get 23.38, or 23.4 to the nearest tenth.

Answer:

v ≈ 34.95ft^3

Step-by-step explanation:

h = 9.8ft

A^B = 10.7ft

V=A^B

h/3 = 10.7 • 9.8/3

≈34.95333ft^3

≈34.95ft^3

Answer:

3rd option

Step-by-step explanation:

([tex]\frac{f}{g}[/tex] )(x)

= [tex]\frac{f(x)}{g(x)}[/tex]

= [tex]\frac{2x^2-5x-3}{2x^2+5x+2}[/tex] ← factorise numerator and denominator

= [tex]\frac{(x-3)(2x+1)}{(x+2)(2x+1)}[/tex] ← cancel (2x + 1) on numerator/ denominator

= [tex]\frac{x-3}{x+2}[/tex]

The simplified form of 10⁹/10⁷ is 100.

The given expression is,

10⁹/10⁷

Since we know that,

Exponentiation is the process of expressing huge numbers in terms of powers. That is, exponent refers to the number of times a number has been multiplied by itself.

Since we also know that,

When base of exponent is same then while dividing we subtract the power of denominator from the power of numerator,

Therefore,

we can write the given expression

10⁹/10⁷ =  [tex]10^{(9-7)}[/tex]

            = 10²

            = 10 x 10

            = 100

Hence,

10⁹/10⁷ = 100

Answer:

75 square inches

Step-by-step explanation:

Area of a Triangle = 1/2 × Base × Height

From the above question:

Base = 30 Inches

Height = 5 inches

Hence:

Area = 1/2 × 30 in × 5 in

Area = 75 square inches

Therefore, the area of one of the triangular pieces of wood that she needs to build the ramp is 75 square inches

Answer:

The possible length of the third side = 1 ft, 2 ft, 3 ft, 4 ft, 5 ft, 6 ft, 7 ft, 8 ft, 9 ft, 10 ft or 11 ft

Step-by-step explanation:

Given;

two side of the triangle, 6 ft and 6 ft

let the third side of the triangle = x

Apply the rules of length of a triangle to determine the third side of the triangle.

Based on this rule:  (6 - 6)  < x < (6 + 6)

                                    0 < x < 12 ft

Therefore, the length of the third side will be greater than 0 but less than 12 ft

The possible length of the third side = 1 ft, 2 ft, 3 ft, 4 ft, 5 ft, 6 ft, 7 ft, 8 ft, 9 ft, 10 ft or 11 ft

Answer:

D 8.053×104 is the answer I think so

Answer:

their hopes will come true

Step-by-step explanation:

Using the formula for calculating amount expressed as;

A = P(1+r)^t

Given

P = $15000

r = 9.6% = 0.096

t = 15years (18-3)

Substitute;

A = 15,000(1+0.096)^15

A = 15,000(1.096)^15

A = 15000(3.9551)

A = 59,326.6

As we can see, the money is even more than twice the original amount, this shows that their hopes will come true

Answer:

a. Yes, the $15,000 will double each 7.5 years. In 15 years, it will double twice.

Step-by-step explanation:

Answer:

The image of both graphs can be seen below:

Both functions will have the same output for an input x₀ if:

f(x₀) = g(x₀)

This means that, for that particular value of x₀, the functions will intersect each other.

So we just need to look at the graph and find the x-value where the functions intersect. (Remember that the x-values are in the horizontal axis)

We can see that it happens at x = 1.

Then the input value that produces the same output value for the two functions is:

x = 1
