Answer:

D. 50% of the budget on car payments and cell phone bills

Step-by-step explanation:

First we take the amount of the car and phone then add it together

So, 275+125 = 400

Then we find 50% or 1/2 of 800

A way to do that is 800 ÷ 2 = 400

So we know that 400 = 400, we know the answer is correct

Anna wants to factor the polynomial p(x)=5x^4+40x. She knows that the sum of cubes formula is a^3+b^3=(a+b)(a^2−ab+b^2).
Artemon [7]

Answer:

Part A:  Option 2, A: Anna’s answer is incorrect. She correctly factored out 5x, but incorrectly identified a and b, so her answer cannot be correct.

Part B:  Option 3, B: 5x(x+2)(x^2−2x+4)

Step-by-step explanation:

p(x) = 5x^4 + 40x

p(x) = 5x(x^3 + 8)

p(x) = 5x(x + 2)(x^2 - 2x + 4)

Part A:  Option 2, A: Anna’s answer is incorrect. She correctly factored out 5x, but incorrectly identified a and b, so her answer cannot be correct.

Part B:  Option 3, B: 5x(x+2)(x^2−2x+4)

Solve 6(2/3x-3)>8. The thing says the question is too short and to add at least 20 more words so ignore this sentence, it's o
xxTIMURxx [149]

<u>Answer:</u>

6(\frac{2x}{3} -3) > 8\\

Solve brackets

6(0.66x-3)>8

Multiply 6 with values in the bracket

<em>So, 6x0.66x and 6x-3</em>

4x- 18> 8

Since 4x and 18 are unlike terms, we will take 18 onto the other side, thus:

4x>8+18

4x>26

<em>Now to find the value of x, divide 4 on B.S</em>

x> \frac{26}{4}

X> 6.5

OR in 'fraction form'

X>\frac{13}{2}

Hope this helps :D

Find the solutions to the equation 4x2 - 8x + 3 = 0
katovenus [111]
<h2>Steps</h2>

So to find the solutions, I will be factoring by grouping. Firstly, what two terms have a product of 12x² and a sum of -8x? That would be -2x and -6x. Replace -8x with -2x - 6x:

4x^2-2x-6x+3=0

Next, factor 4x² - 2x and -6x + 3 separately. Make sure that they have the same quantity on the inside of the parentheses:

2x(2x-1)-3(2x-1)=0

Now you can rewrite it as:

(2x-3)(2x-1)=0

Now, apply the zero product property and solve:

2x-3=0\\2x=3\\x=\frac{3}{2}\ \textsf{OR}\ 1.5\\\\2x-1=0\\2x=1\\x=\frac{1}{2}\ \textsf{OR}\ 0.5

<h2>Answer</h2>

<u>In short, x = 3/2 (1.5) and 1/2 (0.5).</u>

2. 2(x+1.25) = 3.5
dangina [55]

Answer:

x = 0.5

Step-by-step explanation:

Given

2(x + 1.25) = 3.5 ← divide both sides by 2

x + 1.25 = 1.75 ( subtract 1.25 from both sides )

x = 0.5
