The rectangle shown has a perimeter of 66 cm and the given areaIts length is 3 more than five times its width. Write and solve a system of equations to find the dimensions of the rectangle.
Answer:
The area of the rectangle is equal to the base times the height. That is, major side by minor side. In many places we will find how the height is called "h" and the base "b."
Step-by-step explanation:
The dimensions of rectangle are width of 5cm and Length of 28 cm.
What is Rectangle?A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees
The perimeter of rectangle is
Perimeter=2(Length+width)
Given that length is 3 more than five times its width.
L=3+5W
Perimeter=2(3+5w+w)
Perimeter of rectangle is given by 66cm
66=2(6w+3)
Apply distributive property on RHS side
66=12W+6
Subtract 6 from both sides
60=12W
Divide both sides by 12
W=5
L=3+5(5)=25+3=28
Hence the dimensions of rectangle are width of 5cm and Length of 28 cm.

Tell whether the sequence is arithmetic. If it is, identify the common difference -7.-3.1.5....
9514 1404 393
Answer:
yes, 4
Step-by-step explanation:
We assume your sequence is supposed to be ...
-7, -3, 1, 5
First differences are ...
-3 -(-7) = 4
1 -(-3) = 4
5 -1 = 4
These differences are constant, so we can conclude the sequence is an arithmetic sequence, and the common difference is 4.

according to the property √a/√b=√a/b, which choice is equivalent to the quotient below? √72/2
According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.
What is square root?The square root of a number is the value of power 1/2 of that number. In other words, it is the number whose product by itself gives the original number.
Given
[tex]\sqrt{\frac{72}{2} }[/tex]
= [tex]\sqrt{36}[/tex]
= 6
According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex]
[tex]\sqrt{\frac{72}{2} }[/tex] = [tex]\frac{\sqrt{72} }{\sqrt{2} }[/tex]
= [tex]\frac{6\sqrt{2} }{\sqrt{2} }[/tex]
= 6
Thus, according to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.

Please someone help me quick!!!! It's about Domain and range, Please! Anyone!
Answer:
Step-by-step explanation:
They already said the domain of f(x) is x≥0.
The smallest value of f(x) is f(0) = 9.
Range of f(x) is y≥9.
The radicand of a square root must be non-negative, so the domain of f⁻¹(x) is x≥9.
The range is y≥0.

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply.
7 x + 4 and 3 x + 5 + 4 x minus 1
When x = 2, both expressions have a value of 18.
The expressions are only equivalent for x = 4 and x = 6.
The expressions are only equivalent when evaluated with even values.
The expressions have equivalent values for any value of x.
The expressions should have been evaluated with one odd value and one even value.
When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
The expressions have equivalent values if x = 8.
