Answer AND expaination

The product of a number and 3 increased by 5 is 7 less than twice the number which equation can be used to find this number , n?

its -7

the product of a number and 3: 3n

increased by 5: + 5

7 less than: - 7

twice the number: 2n

That gives us the following:

3n + 5 = 2n - 7

You only asked for the equation, not to actually help you solve for n, for note. If you do, just subtract 2n from both sides, and then subtract 5 from both sides.

Answer:

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

         A2 - AB + BA - B2 =

         A2 - AB + AB - B2 =

         A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 16 is the square of 4

Check :  x4  is the square of  x2 

Factorization is :       (x2 + 4)  •  (x2 - 4) 

Equivalent expressions are expressions with equal values

The equivalent expression of [tex]\mathbf{x^6 - 16x^2}[/tex] is [tex]\mathbf{x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]

The expression is given as:

[tex]\mathbf{x^6 - 16x^2}[/tex]

Factor out x^2

[tex]\mathbf{x^6 - 16x^2 = x^2(x^4 - 16)}[/tex]

Express x^4 as (x^2)^2

[tex]\mathbf{x^6 - 16x^2 = x^2((x^2)^2 - 16)}[/tex]

Express 16 as 4^2

[tex]\mathbf{x^6 - 16x^2 = x^2((x^2)^2 - 4^2)}[/tex]

Apply difference of two squares

[tex]\mathbf{x^6 - 16x^2 = x^2((x^2 - 4)(x^2 + 4))}[/tex]

Express 4 as 2^2

[tex]\mathbf{x^6 - 16x^2 = x^2((x^2 - 2^2)(x^2 + 4))}[/tex]

Apply difference of two squares

[tex]\mathbf{x^6 - 16x^2 = x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]

Hence, the equivalent expression of [tex]\mathbf{x^6 - 16x^2}[/tex] is [tex]\mathbf{x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]

Answer:

The area of a rectangle is l x w. So the area of the square is 10 x 10 = 100

The area of a circle is

[tex]\pi \times {r}^{2} [/tex]

The radius of all the circles is 2 inches.

[tex]\pi \times {2}^{2} = \pi \times 4 \: or \: 4\pi[/tex]

There are 4 circles so the area of all four is

[tex]4 \times (4\pi) \: or \: 16\pi[/tex]

To find the area of the shaded part of the square, subtract the area of all the circles, because they are not shaded, from the area of the square, because it is shaded. The difference will be the area of the shaded portion.

[tex]area \: = 100 - 16\pi[/tex]

[tex]area = 100 - 50.6548[/tex]

So the area is approximately 50 Sq in

Answer:

CD = 15

x = 5

Step-by-step explanation:

Since BF ≅ FD and AE ≅ EC, then [tex]EF = \frac{AB + CD}{2}[/tex]

So, [tex]30 = \frac{x^{2} +20 + x^{2} + 22x - 120}{2}[/tex]

[tex]60 = 2x^{2} + 22x - 100[/tex]

[tex]2x^{2} + 22x - 160 = 0[/tex]

[tex]2(x^{2} + 11x - 80) = 0[/tex]

2(x - 5)(x + 16) = 0

x = 5  or x = -16

If x = 5, then CD = [tex]5^{2} +22(5) - 120 = 25 + 110 - 120 = 15[/tex]  

Ix x = -16, then CD = will be a negative number which it cannot be.

Step-by-step explanation:

Answer:Given cot A = 3 over 7 and that angle A is in Quadrant I, find the exact value of cos A in simplest radical form using a rational denominator ... √58=c. cos = 3/√58 To rationalize, multiply the numerator and denominator by √58 ... how do i go about solving a trig identity; that simplify s 1-sin^2 theta/1-cos theta.

Step-by-step explanation:

The value of sin A is [tex]\frac{2\sqrt{29} }{29}[/tex].

The sine of an angle is the trigonometric ratio of the opposite side to the hypotenuse of a right triangle containing that angle.

The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

According to the given question.

We have [tex]cotA = \frac{5}{2}[/tex]

⇒[tex]tanA = \frac{2}{5}[/tex]

From the definition of tangent of an angle.

In  right angled triangle PQR, we can say that

PR = 2 and  RQ = 5

Therefore,

[tex]x^{2} = (PR)^{2} +(RQ)^{2}[/tex]

⇒[tex]x^{2} =(2)^{2} +(5)^{2}[/tex]

⇒[tex]x^{2} = 4 + 25[/tex]

⇒[tex]x^{2} = 29[/tex]

⇒[tex]x = \sqrt{29}[/tex]

Since,

Sine of an angle = opposite side/ Hypotenuse

In triangle PQR

The opposite side w.r.t angle A is PR.

And the hypotenuse is PQ.

Therefore, sine of an angle A is given by

[tex]sinA= \frac{2}{\sqrt{29} }[/tex]

⇒[tex]sinA = \frac{2}{\sqrt{29} } \frac{\sqrt{29} }{\sqrt{29} }[/tex]

⇒[tex]sinA = \frac{2\sqrt{29} }{29}[/tex]

Hence, the value of sin A is [tex]\frac{2\sqrt{29} }{29}[/tex].

The equation (w − 8)(w + 10) simplifies to a quadratic equation

w² + 2w - 10.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given,  (w − 8)(w + 10)

w(w + 10) - 8(w + 10).

w² + 10w - 8w - 10.

Answer:

There are two simple rules to remember: When you multiply a negative number by a positive number then the product is always negative. When you multiply two negative numbers or two positive numbers then the product is always positive.

When dividing negatives and positive number be sure to court the signs. If there are two negatives then they will cancel each other out, so if you have an even number (or zero) of negative signs then the answer will be positive
