are 4x +11x^2 - 3x + 4x^2 and x + 7x^2 eqivalent?

Answers

Answer 1
4x+11x^2-3x+4x^2 = 15x^2 + x
7x^2 = nothing further can be done.
Answer 2
No, these two equations are not equivalent.

4x + 11x^2 - 3x + 4x^2 = x(15^2)

x + 7x^2 = x(1 + 7x)

Jalil is training for a marathon. On Monday, he biked 7.2 miles from his home to a park where he ran 10 laps on a path around a small pond. Then he biked home. Jalil biked and ran a total of 16.9 miles. What is the distance of each lap around the pond?

Please answer quickly.

Answers

Answer:

.25 or 1/4 mile

Step-by-step explanation:

7.2 miles biking x 2 (round trip)= 14.4 miles

Total miles is 16.9-14.4= 2.5 miles left to run 10 times around a small pond. So to find out the distance of each lap around the pool you divide 2.5 miles by 10 laps equals .25 or 1/4 Mike is the distance around the pond.

Step-by-step explanation:

Answer:

18 is A

19 is B

20 is B

Step-by-step explanation:

18 is A because the endocrine system is basically the only system that sends chemicals, mainly hormones throughout the body, and the nercous system is the only system that acts like wiring because of the nerves

19 is B because the nervous system needs the brain to function, the nerves send signals to the brain, and the brain sends signals back through the brain stem

20 is B because it can't be A, since that is multiple tissues and organs, it can't be C because cells are what make up tissues, and it can't be D since organ systems require organs not just tissues

[tex]3^{-1}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex]\frac{1}{a^{n} }[/tex] ⇔ [tex]a^{-n}[/tex]

Given

[tex]\frac{1}{3}[/tex] = [tex]\frac{1}{3^{1} }[/tex] = [tex]3^{-1}[/tex]

When the exponent is a fraction, you're looking for a root of the base. The root corresponds to the denominator of the fraction. For example, take "125 raised to the 1/3 power," or 125^1/3. The denominator of the fraction is 3, so you're looking for the 3rd root (or cube root) of 125

Number of diagonals in a 88-gon = 3740

Step-by-step explanation:

Number of diagonals of a polygon

(where 'n' is the number of sides)

[tex] = \frac{n \times (n - 3)}{2} [/tex]

[tex] = \frac{88 \times (88 - 3)}{2} [/tex]

What is 3x+8 ?
I believe you simplify.

Answers

Step-by-step explanation:

Simplifying x = 3x + -8 Reorder the terms: x = -8 + 3x Solving x = -8 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. x + -3x = -8 + 3x + -3x Combine like terms: x + -3x = -2x -2x = -8 + 3x + -3x Combine like terms: 3x + -3x = 0 -2x = -8 + 0 -2x = -8 Divide each side by '-2'. x = 4 Simplifying x = 4
