4x (2x ^ 3 - x ^ 2-18x + 15)
For this case, the first thing to do is multiply the value of 4x for each of the terms within the parenthesis.
You must take into account the following power properties:
Same exponents are added.
We have then:
(8x ^ 4 - 4x ^ 3-72x ^ 2 + 60x)
Answer:
The standard form is:
(8x ^ 4 - 4x ^ 3-72x ^ 2 + 60x)

Suppose you cut a small square from a square of fabric as shown in the diagram. Write

astra-53 [7]

The area of the large box is x^2 and the area of the small box is 3^2 which is 9. So the area of the leftover part is x^2-9 or (x-3)(x+3).

Hope that helped.

How do I simplify this (sinx)/(secx+1)

pochemuha

Answer:

Step-by-step explanation:

$\frac{sin~x}{sec~x+1} =\frac{sin~x}{\frac{1}{cos~x}+1 } =\frac{sin~x~cos~x}{1+cos~x} \\=\frac{sin~x~cos~x}{1+cos~x} \times \frac{1-cos~x}{1-cos~x} \\=\frac{sin~x~cos~x(1-cos~x)}{1-cos^2 x} \\=\frac{sin~x~cos~x(1-cos~x)}{sin^2x} \\=\frac{cos~x(1-cos~x)}{sin~x} \\=cos ~x(csc~x-cot~x)\\or\\=cot~x(1-cos~x)$

A construction company built a scale model of a new building. the model was built usinga scale of 3 inches= 32 feet. if the buil

Valentin [98]

Answer: 18.75 inches

Step-by-step explanation:

Let the height of the model be represented by x. Therefore, based on the information given in the question, we can form an equation which will be:

3/x = 32/200

Cross multiply

32 × x = 200 × 3

32x = 600

x = 600/32

x = 18.75

Therefore, the height of the model is 18.75 inches
