Answer: See explanation
Step-by-step explanation:
Let the width of the rectangle be x.
The length of a rectangle is 3 times as big as the width. Length = 3x
New width = x + 4
New length = 3x + 4
The new area will be:
a = (3x + 4)(x + 4)
a = 3x² + 12x + 4x + 16
a = 3x² + 16x + 16

Answer:
The measure of angle 6 is 72.
The measure of angle 7 is 108.
Step-by-step explanation:
Corresponding angles are equal. So angle 1, 3, 5 and 7 are all equal.
If you look at angle 1 and 2, they are adjacent angles, so together they add up to 180. So if you subtract 108 from 180 you get 72... and we already established that all corresponding angles are equal, so if angle 2 is 72 degrees, we can conclude that angle 6 is as well.
Match each of the equations with their corresponding graph
What is the sum of x^2 - 3x + 7 and 3x^2 + 5x - 9
Hey there!
The answer to your question is [tex]4x^2+2x-2[/tex]
Given:
[tex]x^2-3x+7[/tex] [tex]and[/tex] [tex]3x^2 +5x-9[/tex]
First, we can start by adding like terms. The following are like terms:
[tex]x^2[/tex] [tex]and[/tex] [tex]3x^2[/tex]
[tex]-3x[/tex] [tex]and[/tex] [tex]5x[/tex]
[tex]7[/tex] [tex]and[/tex] [tex]-9[/tex]
Now, we can add these pairs together, giving us:
[tex]4x^2[/tex]
[tex]2x[/tex]
[tex]-2[/tex]
Now, add all this together, and we get our answer as:
[tex]4x^2 + 2x - 2[/tex]

Simplify each expression by using the distributive property and combining like terms. 3 (2x - 4) - 4x
Given:
The expression is
[tex]3(2x-4)-4x[/tex]
To find:
The simplified form of the given expression by using the distributive property and combining like terms.
Solution:
We have,
[tex]3(2x-4)-4x[/tex]
Using the distributive property, we get
[tex]=3(2x)+3(-4)-4x[/tex]
[tex]=6x-12-4x[/tex]
On combining like terms, we get
[tex]=(6x-4x)-12[/tex]
[tex]=2x-12[/tex]
Therefore, the simplified form of the given expression is [tex]2x-12[/tex].

The sum of two numbers is 51, the difference is 17. Find the numbers.
Answer:
Sum: 34 + 17 = 51
Difference: 34 - 17 = 17
Step-by-step explanation:
math
Answer:
34, 17
Step-by-step explanation:
We can first get the two equations x + y = 51 and x - y = 17 by calling the first number x and the second one y. Next, we can add y on both sides in the second equation to get that 17 + y = x. Now, since we know that 17 + y is equal to x, we can substitute 17 + y in for x in the first equation. We get that 2y + 17 = 51, and if we subtract by 17 on both sides and get that 2y = 34. This means that y is equal to 17, meaning that x is 34.
A horse's heart beats 440 times in 10 minutes. A cow's heart beats 390 times in 6 minutes. Which animal has a greater heart rate?
Answer:
The cow has a greater heart rate than the horse.
Answer:
A cow's heartbeat
Step-by-step explanation:
Horse heartbeat: 440/10 = 44
Cow heartbeat: 390/6 = 65
65 > 44
therefore a cow's heartbeat is greater

(b) A square has an area of 9 cm? What is the length of each side?
Answer:
Each side would have the length of 3.
Step-by-step explanation:
In order to find the area of something you have to multiply the side length and 3 x 3 equals 9.
Answer: The length of each side is 3cm
Step-by-step explanation:
The formula for finding the area of a square is A=a²
-------------------------------------------------------------------------------
Given
The Area is 9 cm
Formula
A=a²
Substitute the value into the formula
A=a²
9=a²
a=√9
a=3
(The reason why it is not ±3 is that length cannot be negative)

Round to the nearest thousand. 6,159
Answer:
6,000
Step-by-step explanation:
To round to the nearest thousand, you keep the digit in the thousands and round up or down, clearing all other smaller units. You round up when the next largest digit, in this case, the hundreds, is 5 or larger. Meanwhile, you round down when it is 4 or smaller. Here it is 1, so you round down to 6,000. If it was 5 or larger, you would round up to 7,000.
6,000
To round a number we look at the number that is right of the one we are rounding. If the number to the left is 4 or under, you round down. If it's 5 or above, you round up.
Hope it helps! Good luck!! :D

True or False: An equation to find Circumference is C = πr2
Answer:
False
Step-by-step explanation:
It's actually C=πd d is diameter or C=πr^2
Answer:
True
Step-by-step explanation: Calculate circumference from area
We are given the area, and by substitution we know that 13π = πr2. We divide out the π and are left with 13 = r2. We take the square root of r to find that r = √13. We find the circumference of the circle with the formula C = 2πr.
