Answer:

x=√-5

Step-by-step explanation:

8-3x=√(4x^2+20)+8

-8                          -8

-3x^2=√(4x^2+20)^2

-3x^2=4x^2+20

-4x^2=20

divide both sides by -4

x^2=-5

√(x^2)=√-5

x=√-5

Step-by-step explanation:

(3)

the values of q decrease as the values of p increase.

this indicates an inverse relationship between the quantities, that is

q = [tex]\frac{k}{p}[/tex] ← k is the constant of variation

to find k use any ordered pair from the table.

using q = 16 when p = 3 , then

16 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )

48 = k

q = [tex]\frac{48}{p}[/tex] ← equation of variation

(4)

the values of q increase as the values of p increase.

this indicates the quantities are in direct variation, that is

q = kp ← k is the constant of variation.

to find k use any ordered pair from the table.

using q = 2 when p = 6 , then

2 = 6k ( divide both sides by 6 )

[tex]\frac{2}{6}[/tex] = k , that is

k = [tex]\frac{1}{3}[/tex]

q = [tex]\frac{1}{3}[/tex] p ← equation of variation

Find a polynomial that represents the area of the
square.

Answers

Answer:

16x² + 72x + 81

Step-by-step explanation:

The area of a square is [tex]s^2[/tex], where s = side. In this case, we're given the side length as 4x + 9.

[tex](4x+9)^2 = (4x+9)(4x+9)[/tex] [tex](4x+9)(4x+9)=(4x)(4x)+(4x)(9)+(9)(4x)+(9)(9)[/tex] [tex]16x^2+36x+36x+81[/tex] [tex]16x^2+72x+81[/tex]

Therefore, the answer is 16x² + 72x + 81.

One just needs to go to his/her calculator and solve it

Answer:

  0.04566210...(8-digit repeat)

Step-by-step explanation:

The quotient of 6 ÷ 131.4 is shown in the attachment. The remainder at the bottom matches the original dividend, so the quotient will be repeating:

  [tex]\dfrac{6}{131.4}=0.\overline{04566210}[/tex]

The division process starts by rewriting the problem to integer division:

  60/1314

(If you like, you could further reduce this to 10/219 by removing a common factor of 6 from numerator and denominator.)

At each stage, the quotient digit is multiplied by the divisor and the result subtracted from the dividend to get a new dividend. Careful attention to the vertical alignment of digits will help ensure that quotient digits have their proper place value.

geometry due tonight

Answers

Answer:

A: 5 CM

B: 2.5 CM

C: ABC approx. equal to EDC (I'm not 100% sure on this one, but it makes most sense.)

I can't help you with number four, I'm sorry. I hope someone else comes along and helps with that!

Step-by-step explanation:

The symbol being used means "approximate equality" meaning that the two angels are alike. So in A, the two sides on the shapes are both 5 cm. On B, since it is half of that side, it would be half of five, making it 2.5 cm. For C, the middle letter is the one touched second. Therefore when you draw the shape it makes the most sense that it's ABC approx. equal to EDC. Not to mention that ABC and the next angel has to match, so since the C is last, it also matches in that spectrum.

For D, I don't know the terminology, I'm sorry.

What is solving inequalities

Answers

An inequality is a comparison of expressions by either "less than" (<), "less than or equal to" (<=), "greater than" (>), or "greater than or equal to" (>=). Note that Html does not support the standard symbols for "less than or equal to" and "greater than or equal to", so we use <= and >= for these relations.
