The Area of a rectangle is Length times Width.
3 * (x+4) = 36
3x + 12 = 36
3x = 24
x = 8. So the length of the rectangle is 12
Answer:
1. 4/12 , 6/8
2. 16/12 , 3/4*
3. 3/2 , 15/14
4. 10/16 , 5/8
10/16 = 5/8
Which ratio forms a proportion with 9/15?
1. 6/10
2. 16/21
3. 36/50
4. 45/70
9/15 = 3/5 which is 6/10
A textbook weighs 2.5 pounds. How many kilograms does the textbook weighs? Round your answer to the nearest tenth of a pound. 1 kg = 2.2 lb
1. 1.1 kg
2. 1.8 kg
3. 5.5 kg
4. 4.7 kg
2.5 lbs * (1 kg/2.2 lbs) =
Solve the proportion using number sense. 2/8 = x/ 48
1. 6
2. 12
3. 16
4. 8
8 * 6 = 48
so what is 2 times 6 ?
or another way
1/4 * 48 = 12
Solve the proportion using cross products. 18/20 = k/110
1. 99
2. 122
3. 3.3
4. 2.9
20 k = 18*110
2 k = 18 *11
k = 9 * 11
Are the ratios 8/12 and 10/25 proportional? Explain
8/12 = 2/3
10/15 = 2/3 so no way 10/25 is 2/3
A 10-acre field produced 750 bushels of corn. At the rate, how much corn can be produced from a 14-acre field?
14 acres * ( 75 bushels/acre)
or
10/750 = 14/x
Step-by-step explanation:
hope this help and plz mark me a brainiest
It is neither.
To be even, f(x) must equal f(-x).
If you substitute -x for x, you'd get
y = (-x)^2 - 2(-x) -8
y = x^2 +2x -8
This is not the same as the original, so this is not even.
To be odd, f(x) must equal -f(-x).
If you take the -x substitution from the last step and then multiply it by -1, you'd have:
y = -1 (x^2 +2x -8)
y = -x^2 -2x +8
This is not the same as the original either.
The function is neither even nor odd.
steps
(x) = 5x^2-3x+7
refine
x=5x^2-3x+7
Switch sides
5x^2-3x+7-x=x-x
Subtract x from both sides
5x^2-4x+7=0
Solve with the quadratic formula
Answer:
Length 
inches
Width 
inches
Step-by-step explanation:
Let 
= length of rectangle, 
= width of rectangle
Given the area and the perimeter of the rectangle, we can write:
So:
Now, we can use substitution to find the value of :
(Quadratic equation)
∴ 
We can use substitution again to find the value of
∵ Length usually refers to the longer side of a rectangle, ∴ length inches and width 
inches.
Hope this helps :)
