Answer:
The length is 18 Cm
The Width Is 6 Cm
Step-by-step explanation:
Write an equation
so perimeter is
2L+2W=P
In this case the perimeter is 48 and one side is 12 cm longer so let’s make the unknown side W, and L as 12+w since the longer side is 12cm longer then the unknown side.
Equation:
2(12+W)+2W=48
Combine like terms and solve the equation
24+4W=48 (I distributed then combined like terms)
Subtract 24 on both sides
4W=24
Isolate the variable by dividing 4 on both sides
W=6
Check:
2(12+6)+2(6)=48?
24+12+12=48✔️

Answer:
CD ≠ EF
Step-by-step explanation:
Using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = C(- 2, 5) and (x₂, y₂ ) = D(- 1, 1)
CD = [tex]\sqrt{(-1+2)^2+(1-5)^2}[/tex]
= [tex]\sqrt{1^2+(-4)^2}[/tex]
= [tex]\sqrt{1+16}[/tex] = [tex]\sqrt{17}[/tex]
Repeat using (x₁, y₁ ) = E(- 4, - 3) and (x₂, y₂ ) = F(- 1, - 1)
EF = [tex]\sqrt{(- 1+4)^2+(-1+3)^2}[/tex]
= [tex]\sqrt{3^2+2^2}[/tex]
= [tex]\sqrt{9+4}[/tex] = [tex]\sqrt{13}[/tex]
Since [tex]\sqrt{17}[/tex] ≈ [tex]\sqrt{13}[/tex] , then CD and EF are not congruent
A car travels at a constant speed.
It travels a distance of 142.2m, correct to 1 decimal place.
This takes 7 seconds, correct to nearest second.
Calculate the upper bound for the speed of a car.
Answer:
see below
Step-by-step explanation:
GivenDistance is 142.2 m, correct to 1 decimal placeTime is 7 seconds, correct to nearest secondTo find:Upper bound for the speedSolutionUpper bound for the speed = upper bound for distance/lower bound for time
Upper bound for distance = 142.25 m (added 0.1/5 = 0.05)Lower bound for time = 6.5 seconds (subtracted 1/2 = 0.5)Then, the speed is:
142.25/6.5 = 21.88 m/s21.88 = 21.9 m/s correct to 1 decimal place21.88 = 22 m/s correct to nearest m/sHow would you write 9^4 as an equivalent expression using a base of 3

3.) A glass of water is being filled up slowly. It initially starts out with 4
ounces of water and fills at a constant rate of 3/2 ounces per minute. How
long will it take to fill the glass if it can hold 16 ounces?
8 minutes
12 minutes
24 minutes
18 minutes
Answer:
8 minutes
Step-by-step explanation:
The amount in the glass after m minutes can be described by ...
a = 4 + 3/2m
We want to find m when a=16, so ...
16 = 4 + 3/2m
12 = 3/2m . . . . . subtract 4
8 = m . . . . . . . . . multiply by 2/3
It will take 8 minutes to fill the glass.

Step-by-step explanation:
3x + 8 = 14
Step 1: Subtract 8 from both sides.
3x + 8 = 14
-8 -8
3x = 6
Step 2: Divide both sides by 3 to get x alone.
3x = 6

x + 5y +3z = 4
4y – z=3
6x – 2y + 4z = 0
Answer:
x = [tex]\frac{1}{4}[/tex]
y = [tex]\frac{3}{4}[/tex]
z = 0
Step-by-step explanation:
You first need to solve for a variable, it won't be as easy as x = 3, you are looking to replace a variable with another equation.
For example, the second equation, 4y-z=3, I can either solve for y or z. It won't be a numerical value but it will get you a step closer.
4y-z=3
4y=z+3
y = [tex]\frac{z}{4} +\frac{3}{4}[/tex]
Then you are able to use substitution to negate one of the variables and solve for the other two variables. I won't type that but I think you get the idea.

A figure in Quadrant II was transformed, and the image is in Quadrant III. Which could not have been the transformation? A. A reflection over the x-axis B. A rotation 90° clockwise C. A translation down D. A rotation 270° clockwise
Answer: B) rotation 90 degree clockwise.
If a figure is in quadrant 2, and we rotate 90 degrees clockwise around the origin, then the figure will end up in quadrant 1 instead of quadrant 3. The four quadrants are numbered so that you start in the upper right corner, and move counterclockwise.
