The first thing you want to do in this equation is get rid of the parenthesis. Because 4-2 is added to (3b+6) you cannot distribute the 2. However, there is an invisible 1 next to the parenthesis, so you can use that. Additionally, I like to change subtraction to addition of a negative number. It makes things a little less confusing.

4+ -2 + 3b + 6

Now just combine the like terms.

4 + -2 = 2
6+ 2 = 8

So the simplified version of your problem is: 3b + 8

4- 2+ (3b+6)
= 2+ 3b+ 6
= 3b + (2+6)
= 3b+ 8

Patrick is keeping track of how far he jogs each morning.
katrin2010 [14]

Answer:

21:50

Step-by-step explanation:

We need to find the ratio of 420 m to 1 km.

We know that,

1 km = 1000 m

So,

The ratio becomes,

\dfrac{420\ m}{1\ km}=\dfrac{420\ m}{1000\ m}\\\\=\dfrac{42\ m}{100\ m}\\\\=\dfrac{21}{50}

So, the required ratio is 21:50.

Please help i need to finish this!!
s2008m [1.1K]

Answer:

20 inches x 26 inches

Step-by-step explanation:

set up an equation: (2x)(x+7)=520

now just solve it

2x^2+14x=520

x^2+7x-260 = 0

factor: (x-13)(x+20)

x = 13 and -20

13 is the only one that works because you can't have a negative side length

13+7=20

13*2=26

lmk if you don't understand how to solve that equation

Answer:

\sqrt{400 \times 400 - 24 \times 400 - 360 \times 400 - 200} \\  \\  = \sqrt{160000 - 9600 - 144000 - 200} \\  \\  = \sqrt{160000 - 9600 - 144000 - 200} \\  \\ = \sqrt{160000 - 153,800} \\  \\  = \sqrt{6200} \\  \\  = 78.74 \\  \\
