Answer:
2[tex]x^{2}[/tex]+x-28
Step-by-step explanation:
To solve binomial multiplication problems you can use the FOIL method. FOIL means first, outside, inside, last, which tells you what order to multiply the terms.
Multiply the first terms,
(2x-7)(x+4)
2[tex]x^{2}[/tex]
Then the outside terms,
(2x−7)(x+4)
8x
Next the inside terms,
(2x−7)(x+4)
-7x
Finally the last terms,
(2x−7)(x+4)
-28
To find the answer put all of the products together and simplify
2[tex]x^{2}[/tex]+8x-7x-28
2[tex]x^{2}[/tex]+x-28

d) S.P. = Rs 400, loss = 20%, C.P. = Rs x, C.P = S.P. + 20% of C.P, Find C.P.
SP = 400
Loss = 20%
CP = x
CP = SP + 20%CP
Therefore,
x = 400 + 20/100x
x = 400 + 1/5x
x - 1/5x = 400
5/5x - 1/5x = 400
4/5x = 400
x = 400 × 5/4
x = 100 × 5
x = 500

1. At the beginning of the month, Michael had $22 in his account at the school bookstore. Use a variable to represent the
unknown quantity in each transaction below and write an equation to represent it. Then represent each transaction on a
number line. What is the unknown quantity in each case?
First he bought some notebooks and pens that cost $16.
Then he deposited some more money and his account balance was $27.
Then he bought a book for English class that cost $39.
Then he deposited exactly enough money so that he paid off his debt to the bookstore.
Answer: -6

Step-by-step explanation:
Which postulate or theorem, if any, could you use to prove DBE is congruent to FCE? If not enough information is given choose not information.
Congruent triangles have equal corresponding angles and sides
The theorem that proves that DBE is congruent to FCE is ASA
From the diagram, we have the following highlights
Angle B is congruent to angle CSide length BE is congruent to side length CEAngles at E on both triangles are congruentThe above highlights represent congruence theorem ASA
Hence, the theorem that proves that DBE is congruent to FCE is ASA

Bridget needs an actor. Actor A is offering her services for an initial $140 in addition
to $20 per day. Actor B is offering her services for an initial $200 in addition to $15
per day.
Write a function g (x) for actor B
Answer:
(x=days) g(x)=15x+200
Step-by-step explanation:
the 200 is a base fee, meaning you cant tag a variable on it and in this case it works as a y-intercept, the 15 dollars a day would be 15x because x is the number of days and to calculate how much it costs to work a few days you multiply the daily rate and the number of days, then add 200 to get your cost.
13(z+4)−6=23(5−z)
PLEASE HELP!!!
Answer:
z = 23/12
Step-by-step explanation:
13(z+4)−6=23(5−z)
Distribute
13z + 52 -6 = 115 - 23z
Combine like term
13z+46 = 115 -23z
Add 23z to each side
13z+23z+46 = 115-23z+23z
36z +46 = 115
Subtract 46 from each side
36z+46-46 = 115-46
36z=69
Divide each side by 36
36z/36 = 69/36
z = 23/12

Shopping: Tax
Situation: You are purchasing four items and want to calculate the tax. The items cost $2.50, $8.75, $3.00, and $10.25. The tax rate is 6%. How much is the tax?
Calculation With Distribution. PLS show all work step by step
The tax is normally done to the total so add the prices up 2.50+8.75+3.00+10.25=24.5
percent is 6%
percent means parts out of 100 so
6%=6/100=0.6/10=0.06/1=0.06* 6% of total* 'of'' translates to multiply
24.50 times 0.06=tax=1.47
Answer:
Step-by-step explanation:
The tax itself is $1.47
You can calculate that by adding up all four items. You should get $24.50. Then, you multiply 24.50 by 6%. When multiplying 24.50 and 6%, make sure you multiply (24.50)(0.06) and not (24.50)(0.6).
The total cost of the items after tax is $23.03 just in case you needed that. Just subtract
24.50 - 1.47

Answer:
The correct options are;
Adding rational expressions
Subtracting rational expressions
Step-by-step explanation:
When adding or subtracting rational numbers, the denominators of the fractions representing the numbers should be equal
Therefore, when adding two or more rational expressions together, the following steps are required;
1) Looking for the Lowest Common Denominator
2) Finding the product of the quotient obtained from dividing the LCD by the denominator of a fraction and the numerator of the fraction
3) Placing the sum (or differences) of the products obtained in the above step as the numerator, while the LCD remain denominator
4) Simplifying the numerator in the above step
5) The faction so obtained, is the sum or difference of two or more rational expressions.

Can the set of lengths be the side lengths of a right triangle?
8 ft, 15 ft, 17 ft
Answer:
yes
Step-by-step explanation:
Using the converse theorem of Pythagoras.
If the longest side squared is equal to the sum of the other 2 sides, then the triangle is right.
longest side = 17 and 17² = 289 and
8² + 15² = 64 + 225 = 289
Since 8² + 15² = 17² then the triangle is right.

Jake spent a three-day weekend on the lake. On Saturday, he rented a pontoon boat for three hours and paid $435. On Sunday, he rented the same boat for five hours and it cost him $625. If he rented the same boat on Monday for just two hours, what is the cost for Jake to rent the pontoon boat for the entire three-day weekend?
Answer:
$265
Step-by-step explanation:
You add $435 and $625 and get $1060 dived that by four and you get
Answer: $1400 for the total 3 days
Step-by-step explanation:
A= (3,435)
B= (5,625)
625-435 190
M= ————— = —— = 95
5-3 2
Y- 435= 95(x-3)
Y - 435= 95x - 285
Y= 95x + 150
95(2) + 150
190 + 150
= $340 for Monday
Finally,
435 + 625 + 340= $1400 for 3 days
