Just multiply the two numbers together. That will give you "meters in 10 hours" If you want it in Km, just divide the answer by 1,000.

\(\sqrt{300}\)

\(\sqrt{100\times3}\)

\(\sqrt{100}\times\sqrt{3}\)

\(\sqrt{10\times10}\times\sqrt{3}\)

\(10\sqrt{3}\)

In triangle ABC, A is four times as large as B. angle C is 20degrees less than B. What is the measure of each angle? 

One angle =B

Angle A =4B

Angle C =B - 20

B + 4B + B - 20 =180

6B =180 +20

6B =200

B=200/6

B=33 1/3, A =33 1/3 x 4 =133 1/3, C=33 1/3 - 20 =13 1/3,

A + B + C =133 1/3 + 33 1/3 + 13 1/3 =180 degrees.

The problem can be reduced to this summation formula:

∑[n(n +1), n=1, 75]=146,300

\(51=7+4\times\sqrt{x}\)

\(51-7=7-7+4\times\sqrt{x}\)

\(44=7-7+4\times\sqrt{x}\)

\(44=0+4\times\sqrt{x}\)

\(44=4\times\sqrt{x}\)

\(\frac{44}{4}=\frac{4\times\sqrt{x}}{4}\)

\(11=\frac{4\times\sqrt{x}}{4}\)

\(11=1\times\sqrt{x}\)

\(11=\sqrt{x}\)

\({11}^{2}={\sqrt{x}}^{2}\)

\(121={\sqrt{x}}^{2}\)

\(121=x\)

\(x=121\)

51=4sqrtx+7

44/4=sqrtx

x=121

It goes on forever

(x+3)(x+3)=x²+6x+9

(x²+6x+9)(x+3)=x³+6x²+9x+3x²+18x+27=x³+9x²+27x+27

(x³+9x²+27x+27)(x+3)=x⁴+12x³+54x²+108x+81

(x⁴+12x³+54x²+108x+81)(x+3)=x⁵+15x⁴+90x³+270x²+405x+243

(x⁵+15x⁴+90x³+270x²+405x+243)(x+3)=

I'll leave the last one to you

1/4+1/2+x=-3/4

add the two fractions together
3/4+x=-3/4
subtract from the other side
x=-3/4-3/4

since subtracting a positive from a negative is the same as adding a negative to a negative you get:

-3/4+(-3/4)=-6/4

x=-6/4 and just simplify if told to.

sqrt(300) => sqrt(100*3) => 10*sqrt(3)

-4 x 1/2  =  -4/1  x 1/2  =  (-4 x1)  / (1 x 2)  =  -4/2 = -2

Use the calculator !   It will work for you....

Take 3 zeros off to make it 9*15

9*10=90

9*5=45

90+45=135

Put 3 zeros back on

9*15=135,000

1. v is greater than or equal to 10

1. v is greater than or equal to 10

Pick any number and multiply the 5 and the 3 by that number and they will be equivalent

5:3

10:6

15:9

20:12      etc, etc...

When they intesect, they are EQUAL.....so, let's set them equal to each other and solve for the 'x' coordinate:

-2x^2 + 4x = 2x-5

-2x^2 +2x+5 = 0

2x^2 - 2x -5 = 0

Yields x = 2.15  and  -1.16

Substitute ino the easiest equation to find the 'y' values

y= 2x-5

y= - 0.7   and  -7.32    

so x,y    =   2.15, -0.7     and   -1.16,-7.32

400km  /  28 l    =  14.28 km/l

5k-2(4k+18)=-51

5k-8k-36=-51.....distribute the -2

-3k-36=-51......combine like terms

-3k=-15..... add 36 to both sides

k=5.....divide both sides by -3
