What is the perimeter of a rectangle which measures 300m long and 78m 60 cm wide?​
Paraphin [41]

Answer:

75720cm or 757.2m

Step-by-step explanation:

300m = 30000cm

78m & 60cm=7860cm

perimeter of rectangle = 2(length) + 2(width)

2(30000) + 2(7860) = 75720cm or 757.2m

I need some help please out
IceJOKER [234]

Question:

Solution:

Let the following equation:

\sqrt[]{12-x}=\text{ x}

this is equivalent to:

(\sqrt[]{12-x})^2=x^2

this is equivalent to:

12-x=x^2

this is equivalent to:

x^2+x-12=\text{ 0}

thus, we can conclude that

x= 3.

Write an equation that is parallel to y = 3x and passes through (-4 , -3)
Anit [1.1K]
The slopes of two parallel lines must be identical.

We have slope m=3, so the slope for the parallel line be the same.

Now, to find an equation that also passes through the given point, we use slope-point form, y-y_1=m(x-x_1), where our point (-4,-3) is substituted for (x_1,y_1).

y+3=3(x+4)

Now, we convert to slope-intercept form as such.

y=3x+12-3\\y=3x+9

And we are done. :) We can verify graphically that these are indeed parallel lines. See attached.

Robert is 13 and his brother is 3 y.o.
X... brother’s age
X+10... Robert’s age
X+10+2... Robert’s age in 2 years
X+2...Brother’s age in 2 years
X+10+2/x+2=3
X=3
X+10=13
