Step-by-step explanation:

(4x+7)^2=(7x+4)^2

16x^2+56x+90=49x^2+56x+16

16x^2+56x+49-49=49x^2+56x+16-49

16x^2+56x=49x^2+56x-33

16x^2+56x-56x=49x^2+56x-33-56x

16x^2=49x^2-33

16x^2-49x^2=49x^2-33-49x^2

-33x^2=-33

x^2=1

x=1,-1

Answer:

1. 8 × X = 8 × 3 = 24.

2. y / 2 = 6 / 2 = 3.

Answer:

1. Area: 24.96 cm^2. Perimeter: 24.2 cm

2. Area: 63.86 cm^2. Perimeter: 35.2 cm

Step-by-step explanation:

1: The area of a parallelogram is equal to base x height. The base is 3.2, and the height is 7.8. 3.2 x 7.8 is equal to 24.96 cm^2. The perimeter of a parallelogram is 2(width + length). The width is 3.2, and the length is 8.9. 2(3.2 + 8.9) = 2(12.1) = 24.2 cm.

2: The area of a parallelogram is equal to base x height. The base is 10.3, and the height is 6.2. 10.3 x 6.2 = 63.86 cm^2. The perimeter of a parallelogram is 2(width + length). The width is 10.3, and the length is 7.3. 2(10.3 + 7.3) = 2(17.6) = 35.2 cm.

To solve this problem, we need to use trigonometric ratio SOHCAHTOA.

In this case, we have the value of opposite and angle and we need to find the adjacent to the angle. The tangent of the angle would be perfect for this.

[tex]tan\theta = \frac{opposite}{adjacent} \\tan11.4 = \frac{3900}{x}\\x = \frac{3900}{tan11.4}\\ x = 18506.83m[/tex]

I think this is right, good luck!

Answer:x = (125,0)    y = (0,275)

Step-by-step explanation:

Answer:

The difference is 1

Step-by-step explanation:

Because the ratio is 5:4, there are 5/4 times as many adult cats as kittens, or 4/5 times as many kittens than adult cats.

So you do:

24 × 5/4

= 24/1 × 5/4

= 120/4

= 30

31 - 30 = 1

Answer:

65° and 65°

Step-by-step explanation:

The base angles of an isosceles triangle are congruent.

let the base angle be x then sum the angles and equate to 180°

x + x + 50° = 180° ( subtract 50° from both sides )

2x = 130°  ( divide both sides by 2 )

x = 65°

The measures of the 2 angles are 65° and 65°

After simplification, There are 0.625% of 600 is 3 3/4.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The number of 600 is 3 3/4.

Let value of percent = x

Hence, We get;

⇒ x% of 600 = 3 3/4

⇒ x/100 × 600 = 15/4

⇒ 6x = 15/4

⇒ x = 15/24

⇒ x = 0.625

Thus, There are 0.625% of 600 is 3 3/4.

Answer:

Given below.

Step-by-step explanation:

For upper bound, the length is 88.5 cm and width is 49.5 cm

So, area of rectangle, TV = length * width

                                          =  88.5  *  49.5

                                          = 4380.75 cm²

So, perimeter =  2( length + width )

                       = 2( 88.5 + 49.5 )

                        = 276 cm

For lower bound, the length is 87.5 cm and width is 48.5 cm

So, area of rectangle, TV = length * width

                                          =   87.5 *  48.5

                                          = 4243.75 cm²

So, perimeter =  2( length + width )

                       = 2(  87.5 + 48.5 )

                        = 272 cm

Here

Note the formulas

[tex]\boxed{\bf Perimeter=2(L+B)}[/tex]

[tex]\boxed{\bf Area=LB}[/tex]

Now

[tex]\\ \tt\hookrightarrow Perimeter=2(88+49)=2(137)=274cm[/tex]

[tex]\\ \tt\hookrightarrow Area=88(49)=4312cm^2[/tex]

Answer:

   5x/7y^3

Step-by-step explanation:

Something to the power of -1/2 is saying 1 over square-root of that something. Let's pretend x is that something. If we have something like this [tex]x^{-\frac{1}{2} }[/tex], then it can be written like this: [tex]\frac{1}{\sqrt{x}}[/tex].

In our problem, we have the chunk to the -1/2 power. So the reciprocal of the chunk would become [tex]\sqrt{\frac{25x^{2} }{49y^{6}}[/tex]

It's easy to solve now. The square root of the numerator becomes 5x and the denominator becomes 7y^3. The simplified version is [tex]\frac{5x}{7y^\power{3}}[/tex]

Answer:

y = 4(2x) - 3

Step-by-step explanation:

linear functions are written like y =mx + b or y = kx

They must have "x" in it and there cannot be a square root or exponent near x.

y = -2 does not have an x therefore it is not a linear equation

x² + y = 1 has an exponent so write away we can eliminate this because linear equations cant have exponents

y = 2√x has a square root so we can eliminate this answer choice as well

y = 4(2x) - 3 simplifies to y = 8x - 3 which is put in y = mx + b which is linear therefore this is the answer
