area of rectangle = l*b
= (3x-y+4) ( X+7)
= 3x²-xy + 4x+21x-7y+28
= 3x²-xy +25x-7y +28
Area of square = l²
= (x-2)²= x²- 4x +4
area of shaded region=( 3x²-xy +25x-7y +28) -(x²- 4x +4)
=2x²-xy +29x-7y+24
Step-by-step explanation:
Given the triangle that has a base of five less than triple the height. The height is 2x+6.
Part A: Determine the expression that represents that area of the triangle.
Answer:
A = 0.5(2x+6)(6x+13) = 6x² + 49x + 78Step-by-step explanation:
H = 2x+6 - the hight
3H = 3(2x+6) - triple the hight
3H-5 = 3(2x+6) - 5 - five less than triple the height
Area of triangle: A = 0.5BH
B = 3(2x+6)-5 = 6x + 18 - 5 = 6x + 13
H = 2x+6
So:
A = 0.5(2x+6)(6x+13) = (x+6)(6x+13) = 6x² + 13x + 36x + 78
A = 6x² + 49x + 78

The length of a rectangular room is 8 feet more than twice the width. If takes perimeter of the room is 124 feet, what are its dimensions?
Hey there! I'm happy to help!
Let's call the length and width L and W respectively.
L=2W+8
2W+2L=124
We plug our value of L into the second equation and solve for W.
2W+2(2W+8)=124
We undo the parentheses with the distributive property.
2W+4W+16=124
Combine like terms.
6W+16=124
Subtract 16 from both sides.
6W=108
Divide both sides by 6.
W=18
We plug this W value into the first equation to solve for L.
L=2(18)+8
L=36+8
L=44
So, the length is 44 feet and the width is 18 feet.
Have a wonderful day! :D

At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 calories and twice as many chicken wings as there are sliders. write a system of equations that could be used to determine the number of chicken wings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.
Answer:
x = 2y --------(1)
75x + 250y = 800 ---------(2)
Step-by-step explanation:
Let the number of chicken wings be x
And the number of sliders be y
x = 2y --------(1)
75x + 250y = 800 ---------(2)
The system of equation is x = 2y and 75x + 250y = 800.
Important information:At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 calories and twice as many chicken wings as there are sliders. here we assume the number of chicken wings be x and number of sliders be yEquation:x = 2y --------(1)

Help on this question pls
Answer:
The answer is D, -11 degrees.
Step-by-step explanation:
Angle RQP is total sum of angles RQU, (96 + x) and UQP, (x + 57).
Angle RQP = 131.
(96 + x) + (x + 57) = 131
153 + 2x = 131
2x = -22
x = -11.
Therefore, answer is -11 degrees.

HELP!!!!!!! Correct answers only!!!! Will give brainliest!!!!!! One-third cup of black beans provides 20% of the potassium you need daily. You must get the remaining 1,360 milligrams from other sources. How many milligrams of potassium should you consume daily?
Answer:
1,700 MG
Step-by-step explanation:
1, 360 / 2 = 40% of the daily amount since 20% is taken from the beans.
1360 / 2 = 680
680 (40%) / 2 = 340, which is 20%.
Then, add 20% (340) to 1, 360, which gives the full percentage.

(a) Olivia deposits $8600 in a bank. The interest rate is 2.6% per annum.
Find the total interest she will earn in 4 years.
Answer:
Below in bold.
Step-by-step explanation:
You do not say if the interest is simple or compound.
Simple Interest: I = PRT/100
= (8600* 2.6 * 4)/ 100
= $894.40.
Compound Interest:- amount after 4 years
= 8600(1 + 0.026)^4
= $9529.89
So the compound interest
= 9529.89 - 8600
= $929.89.
