3(6x + 5) will be equivalent expression of 9x - 4 + 4x + 5x + 19 so option (A) will be correct.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
Given the expression,
9x - 4 + 4x + 5x + 19
By adding variables and constants individually
(9x + 4x + 5x) + (-4 + 19)
⇒ 18x + 15
Taking common 3
⇒ 3(6x + 5)
Hence "3(6x + 5) will be equivalent expression of 9x - 4 + 4x + 5x + 19".

Answer:
Step-by-step explanation:
SOLUTION:
The opposite sides of a rectangle are parallel and congruent. So, ZY = WX.
2x + 3 = x + 4

A certain forest covers an area of 2100 km^2. Suppose that each year this area decreases by 5.25%. What will the area be after 6 years
Answer:
The area after 6 years is [tex]1519.49km^2[/tex]
Step-by-step explanation:
Given
[tex]a = 2100[/tex] --- Initial Value
[tex]r = 5.25\%[/tex] --- Rate
Required
Determine the area after 6 years
Because the area reduces,, the following formula will be used to solve the question.
[tex]y = a*(1 - r)^t[/tex]
Here
[tex]t = 6[/tex]
So, we have:
[tex]y = 2100*(1 - 5.25\%)^6[/tex]
Convert percentage to decimal
[tex]y = 2100*(1 - 0.0525)^6[/tex]
[tex]y = 2100*(0.9475)^6[/tex]
[tex]y = 1519.47866516[/tex]
[tex]y = 1519.49[/tex] -- approximated
The area after 6 years is [tex]1519.49km^2[/tex]

the doctor recommended that Matt increase the number of calories you consume from 2000 to 2800 by what percent did the number of calories increase
Answer:
40% number of calories have increased
Step-by-step explanation:
Old Value ( Calories consume before) = 2000
New Value (increase in Calories consumed) = 2800
We need to find by what percent did the number of calories increase
To find percent increase, the formula used is:
[tex]Percent\: increase=\frac{New\:Value-Old\:Value}{Old\:Value}\times 100%[/tex]
Putting values in formula and finding percent increase
[tex]Percent\: increase=\frac{New\:Value-Old\:Value}{Old\:Value}\times 100\%\:\\Percent\: increase=\frac{2800-2000}{2000}\times 100\%\: \\Percent\: increase=\frac{800}{2000}\times 100\%\: \\Percent\: increase=0.4\times 100\%\: \\Percent\: increase=40\%[/tex]
So, 40% number of calories have increased

Using sides of a triangle rule, the inequality gives the range of possible values for x is 5 < x < 9.
What is sides of a triangle rule?
The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side.
Given that two sides of triangle are 2 and 7 inches.
Let the third side be x inches.
x < 2+7 ⇒ x < 9
7 < 2 + x ⇒ x > 5
2 < 7 + x, which is true for any positive value of x.
Thus, 5 < x < 9.

Maggie stacked a box that was 83 centimeters (cm) tall on top of a box that was 128 centimeters. How tall was the stack of boxes in meters and centimeters?
Answer:
211 centimeter ; 2.11 meter
Step-by-step explanation:
Given that:
Height of box 1 = 128 cm
Height of box 2 = 83 cm
Stacking box 2 on the box 1 :
Height of stack :
Height of box 1 + height of box 2
128 cm + 83 cm = 211 cm
Converting 211 cm to meter :
100 cm = 1 m
211 cm = (211 / 100) m
= 2.11 meter

Regina is buying a new car. She sees two advertisements in the paper for the same car at two different prices from two different dealerships. Both dealers are offering a simple-interest loan for the price of the car. A photo of car includes two ads. Ad A shows the vehicle priced at twenty-four thousand two hundred dollars at six point five percent interest and an unknown number of years. Ad B shows an unknown price, at a five point three percent interest over nine years. Question 1 Part A Regina calculates that to buy the car in Ad A, the loan would ultimately cost her $41,503. Over how many years is the loan in Ad A to be paid back?
Answer:
11 years
Step-by-step explanation:
Given that:
Advert A:
Principal, p = $24,200
Interest rate, r = 6.5% = 6.5/100 = 0.065
Time, t =?
Total Repayment, A = $41,503
Using the relation :
A = p(1 + rt)
Plugging our values
41503 = 24200(1 + 0.065t)
41503 / 24200 = 1 + 0.065t
1.715 = 1 + 0.065t
1.715 - 1 = 0.065t
0.715 = 0.065t
t = 0.715 / 0.065
t = 11 years
Loan in Advert A will be paid back in 11 years
Answer:
11 years
Step-by-step explanation:
Given that:
Advert A:
Principal, p = $24,200
Interest rate, r = 6.5% = 6.5/100 = 0.065
Time, t =?
Total Repayment, A = $41,503
Using the relation :
A = p(1 + rt)
Plugging our values
41503 = 24200(1 + 0.065t)
41503 / 24200 = 1 + 0.065t
1.715 = 1 + 0.065t
1.715 - 1 = 0.065t
0.715 = 0.065t
t = 0.715 / 0.065
t = 11 years
Loan in Advert A will be paid back in 11 years
