Answer:
Breadth/width = 1.936cm, length = 7.746cm
Step-by-step explanation:
Perimeter of a rectangle would be [tex]2L*2W=60cm[/tex] in this case. Breadth is width.
But we can rewrite this equation given that the width is 1/4 the length. This means 4 of the widths would equal one length.
[tex]W=\frac{1}{4}L[/tex]
[tex]L=4W[/tex]
We can substitute L with the 4W
[tex]2(4W)*2(W)=60cm[/tex]
Now we can just solve for the width W.
[tex]8W*2W=60\\16W^2=60\\W^2=\frac{15}{4} \\W=\sqrt{\frac{15}{4} } \\W=\frac{\sqrt{15} }{2}=1.936cm[/tex]
We now know the width is about 1.936cm
We can find the length given our formula before of [tex]L=4W[/tex]
[tex]L=4(\sqrt{\frac{15}{2} } )=2\sqrt{15} =7.746cm[/tex]
So the breadth/width is 1.936cm and the length is 7.746cm.

Answer: 9
12-1.5t
Step-by-step explanation:
1.5*2=3
12-3=9
1.5*t=1.5t
If he used 3 gallons of gas. Then the amount of the gas in the tank after driving for 2 hours will be 9 gallons.

Mason is driving on a long road trip. He currently has 12 gallons of gas in his car. Each hour that he drives, his car uses up 1.5 gallons of gas.
Then the amount of the gas in the tank after driving for 2 hours will be
The amount of gas used in 2 hours will be
Used gas = 2 x 1.5
Used gas = 3 gallons of gas
Then the remaining amount will be
Remaining amount of gas = 12 - 3

Solve the following equation using the completing the square method:
x2+8x=3
Answer:
x= plus or minus square root of 19 -4
Step-by-step explanation:
x^2+8x ___=3
take half of your b term (8) and then multiply by two and add or subtract it to both sides
x^2+8x+16=3+16
then combine like terms
x^2+8x+16=19
then factor your quadratic equation
(x+4)^2=19
now solve for x
take the square root of (x+4)^2 to get rid of the ^2
you then also have to square the 19 because what you do to one side you have to do to the other
(x+4)= square root of 19
subtract 4 from both sides
x= plus or minus square root of 19 -4
Answer:
Step-by-step explanation:
Divide the coefficient of x by 2
8/2 = 4. Now find the square of 4 = 4² = 16
Add 16 to both sides of the equation
x² + 8x + 16 = 3 + 16
x² + 2* x * 4 + 4² = 19
{Compare with a² + 2ab + b² = (a + b)² }
(x + 4)² = 19
Both sides take square root,
[tex]\sqrt{(x+ 4)^{2}}=\sqrt{19}\\\\x + 4 = \sqrt{19}[/tex]
x + 4 = ± 4.36
x + 4 = 4.36 ; x + 4 = -4.36
x = 4.36 -4 ; x = -4.36 - 4
x = 0.36 ; x = - 8.36

Plot the point (11, 7) on the coordinate plane.
Answer:
Step-by-step explanation:
When you're asked to plot a point on a coordinate plane just remember that the coordinate given is of the form [tex](x,y)[/tex].
So, first, we need to plot 11 on the [tex]x[/tex]-axis (the line going left to right, horizontal) then plot 7 on the [tex]y[/tex]-axis (the vertical line)
So we first go 11 units to the right along the [tex]x[/tex]-axis then go up 7 units along the [tex]y[/tex]-axis.
