18. Write an expression to represent the area of the shaded region in simplest form. Please help it's due tomorrow
(no links btw) and I will give brainlyest!
Answers
Answer:
(x^2 + 2x - 21) sq units
Step-by-step explanation:
Area of the shaded region = Area of the larger rectangle - Area of smaller rectangle
Area of the larger region = x(x+2)
Area of the larger region =x^2 + 2x
Area of the smaller rectangle = 3 * 7
Area of the smaller rectangle = 21 sq. units
Area of the shaded region = x^2 + 2x - 21
Hence the required expression is (x^2 + 2x - 21) sq units

Answer:
? = 13
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
?² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )
? = [tex]\sqrt{169}[/tex] = 13
Answer:
13
Step-by-step explanation:
If we use the Pythagorean theorem we have
hypothenuse^2 = 12^2 + 5^2 = 144 + 25 = 169
hypothenuse = √169 = 13
Investors buy a studio apartment for 140,000 of this amount they have a down payment of 28,000 their down payment is what percent of the purchase price what percent of the purchase price would a 63,000 down payment be
Answers
Answer:
a. 20%
b. 45%
Step-by-step explanation:
The total cost of the studio apartment is $140,000.
The down payment is $28,000.
Percentage of down payment to purchase price is:
= 28,000 / 140,000 * 100%
= 20%
b. Percentage of down payment of $63,000 to purchase price is:
= 63,000 / 140,000 * 100%
= 45%

In indices
[tex](x^m)^n = x^{mn[/tex]
Applying to solve the question
[tex](2x^2 y^{-2} / y^5)^{-3}\\\\= \frac{2x^{-6}y^6}{y^{-15}}\\= 2x^{-6} * \frac{y^6}{y^{-15}} \\= 2x^{-6} * y ^{6-(-15)}\\= 2x^{-6} * y ^{6+15}\\= 2x^{-6} * y ^{21}\\= 2x^{-6}y ^{21}\\\\[/tex]

Gilbert purchased a car for 34000. The car depreciates at a rate of 14% per year. The exponential function that represents this situation is y = 34000(0.86)^x.
What is the change factor for this function?
Answers
Answer:
.86
Step-by-step explanation:
Exponential function formula
[tex]y = a ( 1 + or - r ) ^t[/tex]
where a = initial value
r = rate of change
and t = number of years
given the equation y = 34000(0.86)^x.
r = .86
Hence the change factor is .86

Step-by-step explanation:
Since this is division for a fraction, you do keep, change, flip.
First, you keep the first fraction.
3 1/3 ÷ 2/3
Then, you flip the ÷ to a ×.
3 1/3 × 2/3
Next, you flip the 2nd fraction.
3 1/3 × 3/2
Now you can make the mix number an improper fraction.
10/3 × 3/2
Finally multiply across.
10/3 × 3/2 = 30/6
Simplify.

One of the legs of a right triangle measures 8 cm and the other leg measures 12 cm.
Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
Answers
Answer:
14.4 cm
Step-by-step explanation:
We solve the above question using Pythagoras Theorem
The formula is given as:
c ² = a² + b ²
Where:
c = Hypotenuse
a = 8cm
b = 12 cm
Hence,
c² = 8² + 12²
c² = 64 + 144
c² = 208
We square root both sides
c = √(208)
c = 14.422205102 cm
Approximately to the nearest tenth = 14.4 cm

If the square below is enlarged by a scale factor of 2, what will be the area of the new square? 184 square units 188 square units 192 square units 196 square units
Answers
Answer:
256square units
Step-by-step explanation:
Since we are not given a diagram. Let us assume the side length of the given square is 8 units
If the the square is enlarged by a scale factor of 2, the side length of the new square will be 2 * 8 = 16units
Since area of a square = L²
Hence the area of the new square = 16²
area of the new square = 256 square units
Hence the area of the new square is 256square units
Note that the side length of the original square was assumed. The values can change depending on the side length of the original square before enlargement
