Answer: x^2 + 23x + 49
Step-by-step explanation:
The area of the shaded region is the area of the big rectangle minus the square
area of rectangle
area = bh
b = 2x + 5
h = x + 10
area = (2x+5)(x+10) FOIL
= 2x^2 + 20x + 5x + 50
= 2x^2 + 25x + 50
area of square
area = s * s
s = x + 1
area = (x+1)(x+1) FOIL
= x^2 + x + x + 1
= x^2 + 2x + 1
area of shaded region
now subtract rectangle - square
(2x^2 + 25x + 50) - (x^2 + 2x + 1)
= 2x^2 + 25x + 50 - x^2 - 2x - 1 combine like terms
= x^2 + 23x + 49
Answer:
(x² + 23x + 49) units²
Step-by-step explanation:
(x + 10)(2x + 5) - (x + 1)²
(2x² + 20x + 5x + 50) - (x² + 2x + 1)
2x² + 25x + 50 - x² - 2x - 1
x² + 23x + 49

Answer: The possible side lengths are either 16 inches or 20 inches
Step-by-step explanation: The aquarium is in the shape of a cube which suggests that, all dimensions (length, width and height) are equal.
If it can hold 4096 cubic inches of water, then the volume of water in it can be calculated as follows;
Volume = L x W x H
Knowing that all three dimensions are the same the formula can be re-written as;
Volume = L³
4096 = L³
Add the cube root sign to both sides of the equation
∛4096 = ∛L³
16 = L
Also if it can hold up to 8000 cubic inches of water, then the volume of water in it can be calculated as;
Volume = L³
8000 = L³
Add the cube root sign to both sides of the equation
∛8000 = ∛L³
20 = L
Therefore, if the aquarium can hold between 4096 and 8000 cubic inches of water, then the side lengths are either 16 inches or 20 inches

Cost Price of a stock of Bree Medical Supply = 31 1/2
= 63/2 dollars
Cost at which the 20 stocks of Bree Medical Company bought = (63/2) * 20
= 630 dollars
Sale price of each stock = 35 1/4 dollars
Sale price of each stock = 141/4 dollars
Sale price of 20 stocks = (141/4) * 20
= 705 dollars
Then amount of profit made = (705 - 630) dollars
= 75 dollars
So it can said that the statement you made a profit of $75 and so option "D" is the correct option.

The angle supplementary to the angle 39° Mabel measured is C. 129°.
What are supplementary and complementary angles?
When the sum of the two angles is 180° they are said to be supplementary.
When the sum of the two angles is 90° they are said to be complementary.
Given, Mabel measured an angle on her math worksheet with her protractor. The angle measured 39°.
Therefore, The angle supplementary to the angle she measured is,
= (180 - 39)°.
= 129°, As the sum if the sum of two angles are supplementary their sum is
180°.
