If segments DE and AB are parallel, which of the following expressions will help Eshaal determine the length of segment BC?
BC = CE
BC equals AC times CE all over CD
BC equals AC times DE all over CE
BC = AC

PS:
Can I have Brainliest?
The correct statement is BC equals to AC times CE all over CD.
We have, If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally. this is known as the triangle proportionality theorem.
Given, DE and AB are parallel
So, [tex]\frac{BC}{CE} =\frac{AC}{CD}[/tex]
[tex]BC = \frac{AC\times CE}{CD}[/tex]
Therefore in statement form we say that BC equals to AC times CE all over CD.

Fadil sells televisions. He earns a fixed amount for each television and an additional $20 if the buyer gets an extended warranty. If Fadil sells 11 televisions with extended warranties, he earns $770. How much is the fixed amount Fadil earns for each television
Answers
Answer:
770.00 divided by 11 = total cost of 70.00 per tv, subtract 20.00 for extended warranty, TVs were 50.00 each.
Answer:
$50
Step-by-step explanation:
Given: The amount earned by Fadil on selling 11 televisions= $770
Therfore, the amount he earned on selling 1 television=
[tex] \frac{770}{11} [/tex]
=$70
Since, he sold televisions with extended warranty and he earns $20
Then, the fixed amount Fadil earns for each television= $70-$20=$50
So, Fadil earns $50 as the fixed amount for each television.

The result when we subtract 3x^2 + 7x - 4 from 8x^2 - 6x + 2 is 5x^2 - 13x + 6.
Subtracting polynomials is a method of subtracting polynomials by converting the signs to the opposite sign. It is done in two methods - vertically and horizontally.
Using the method in subtracting polynomials horizontally:
Step 1: Arrange the polynomials in their standard form.
Both 3x^2 + 7x - 4 and 8x^2 - 6x + 2 are in their standard form(exponents in decreasing order)
Step 2: Place the polynomial next to each other horizontally.
(8x^2 - 6x + 2) - (3x^2 + 7x - 4)
Step 3: Distribute the negative sign to the second polynomial.
(8x^2 - 6x + 2) - 3x^2 - 7x + 4
Step 4: Combine the like terms and arrange them in decreasing order.
8x^2 - 3x^2 - 6x - 7x + 2 + 4
Step 5: Perform the calculations.
5x^2 - 13x + 6

In a right angled triangle, right angle at C, if AB = 32 cms and sin B=5 by 8 find AC
Answers
The numerical length of side AC is 20 units
How to determine the length of AC?The given parameters are:
AB = 32 cm
sin(B) = 5/8
The possible triangle is added as an attachment
From the attached triangle, we have the following sine ratio
sin(B) = AC/AB
This gives
5/8 = AC/32
Multiply both sides of the triangle by 32.
So, we have
AC = 32* 5/8
Evaluate the product
AC = 20
Hence, the numerical length of side AC is 20 units

Answer:
{-1, -3, -7}
Step-by-step explanation:
Dividing the given polynomial by (x+1) yields a quotient of x^2 +10x +21. That factors as (x+3)(x+7), so the three zeros are ...
x ∈ {-1, -3, -7}
__
The factors of x^2 +10x +21 are found by looking for factors of 21 that have a sum of 10. Those factors are 3 and 7, so the complete factorization of f(x) is ...
f(x) = (x +1)(x +3)(x +7)
The zeros are the values of x that make these factors be zero. In each case, that x-value is the opposite of the constant in the binomial term.

4.What could happen if you do not keep track of the checks you write?
5.What is it call when you put money into your account?
Answers
Answer:
1. I believe that the difference between keeping an account & and a fee for an account is checking accounts don't have much interest, and are better for more purchases in bills and payments. For a fee like saving accounts, it's better for saving the money and such things like that.
2. You must require your two forms of identification. Which is a Social security card, driver's license, a state ID, and a passport or birth certificate at most. This is what you need to have with you when opening a checking account.
3. Use decimal points in order to tell the differences between dollars and cents. Those can easily mix up. Put a accurate date of what time you signed the check. Put out the amount in words, it helps a lot just incase they can't read the numbers.
4. If you could not keep the track of checks you write, it could mean that you have bounced the check. "Bouncing" the check means that you don't have enough money in your account to provide paying for it. Therefore, the bank gives you multiple fees and a organizer of all checks that you could not afford because you were not keeping up with the track of checks you wrote.
5. This is called a cash deposit.
