Valerie's goal is to study more than 1 1/4 hours each night.

Which shows the possible number of hours she might study to reach this goal?

A.

h < 1 1/4

and h may be up to 3 hours.

B.

h ≥ 1 1/4

and h may be up to 3 hours.

C.

h > 1 1/4

and h may be up to 30 hours.

D.

h > 1 1/4

and h may be up to 3 hours.

Answers

D, because she wants to study more than 1 1/4 hours. > is the greater sign, It can't be C because there is not 30 hours in a day, It can't be B because she wants to study more than 1 1/4 hours not equal to it. It wouldn't A because thats the less than sign.

Consider the polynomial p(x)=8x3+12x2+2x+3.Part A: What is the correct factorization of p(x)=8x3+12x2+2x+3 over the integers?

Part B: What method is used to factor p(x)=8x3+12x2+2x+3?

Select one answer for Part A and select one answer for Part B.

B: perfect-square trinomial
B: grouping
A: (2x+3)(4x+1)
B: sum of cubes
A: (4x2+1)(2x+3)
A: (2x+3)(4x2+6x+1)

Answers

A: $(4x^2+1)(2x+3)$

B: grouping

Step-by-step explanation:

We are given the polynomial: $p(x)=8x^3+12x^2+2x+3$

Part A: What is the correct factorization of $p(x)=8x^3+12x^2+2x+3$ over the integers?

We need to factorize the term $p(x)=8x^3+12x^2+2x+3$

Factorizing by grouping:

$p(x)=8x^3+12x^2+2x+3$

$p(x)=(8x^3+12x^2)+(2x+3)$

$p(x)=4x^2(2x+3)+1(2x+3)$

$p(x)=(4x^2+1)(2x+3)$

So, factors of the term $p(x)=8x^3+12x^2+2x+3$ are $p(x)=(4x^2+1)(2x+3)$

Part B: What method is used to factor p(x)=8x3+12x2+2x+3?

The method used to factor the given polynomial is grouping.

We group the terms and then find the common terms in that specific group

So, the answers are:

A: $(4x^2+1)(2x+3)$

B: grouping

What is the relationship between angle 1 and angle 5

Answers

Answer:

○ b Corresponding Angles

Step-by-step explanation:

These two angles are a mirror,so they correspond.

I am joyous to assist you anytime.

Final answer:

Angle 1 and angle 5 are alternate interior angles with the same measure.

Explanation:

Angle 1 and angle 5 are alternate interior angles formed by a transversal line intersecting two parallel lines. Alternate interior angles are equal in measure, which means that angle 1 and angle 5 have the same measure. This relationship holds true regardless of the specific measurements of angle 1 and angle 5.

Answers

The correct answer is B and D.

Answer choice A is a ray, not a plane.
Answer choice C is not even a plane.

M is the name of the plane. Also, plane SRX is a plane because it contains points that are not all in a straight line and are on the same plane.

CX is a line not a plane. You can tell from the line symbol above CX.
SRX are all points on a plane and define the plane by existence.
g is a line but not a plane.
Plane M is a plane as it is a two-dimensional flat surface consisting of lines and points.

I would choose B and D. However, the answer choices define line g as a plane so you might want to look further into it.

What is 2x times x squared?

Answers

We want to multiply the monomial $2x$ by the monomial $2x^2$ .

Remember that to multiply monomials we need to use the laws of exponents; in this case, the law for multiplying powers with the same base. The rule says that, when you multiply powers of the same base, you just need to add the exponents: $(a^m)(a^n)=a^(m+n)$ , $(x^2)(x^4)=x^(2+4)=x^6$ . Also, is worth pointing out that the exponent of a variable with no exponent is 1: $x=x^1$ .

Remember that we also need to multiply their coefficients , which are the numbers that multiply the variables; again, variables with no numbers have a coefficient of 1, so $x=1x$ . Multiply coefficients is easy, you just need to multiply them as you usually do with everyday numbers.

Let's apply all of that to our multiplication:

$(2x)(x^2)=(2x^1)(1x^2)=2*1x^(1+2)=2x^3$

We can conclude that 2x times x squared is 2x cubed.

$2x$ times $x$ is $\boxed{\bf 2x^(3)}$ .

Further explanation:

A monomial is an expression which contains one term and a monomial includes numbers and variables which are multiplied together. The constant term is multiplies with an another constsnt term and the variable is multiplies with an another variable term.

Law of exponent:

Product with same base: If we multiply the same bases with different exponents then the base remains the same and the exponents are added in the final product.

Calculation:

Now, we are given the two monomials as $2x$ and $x^(2)$ .

Multiplying both the monomials as follows:

$\boxed{2x\cdot x^(2)}$

Here, $x$ is a variable and $x$ has power $1$ in the first monomial and $x$ has power $2$ in the second monomial.

Using the mentioned law of exponents as the variable $x$ is similar in both the monomial and add the powers of both as follows:

$\boxed{\begin{aligned}2x\cdot x^(2)&=2x^(1+2)\n&=2x^(3)\end{aligned}}$

Therefore, $2x$ times $x$ is $\boxed{\bf 2x^(3)}$ .
