<span>The side b is called base of the right triangle, the 7 cm side is the height, and 13 cm is the hypotenuse. We can get the value of b by applying Pythagoras formula, which is b² + 7² = 13 ², and then b² =169 – 49 = 120, from where we get b= sqrt(120). Finally the true answer is A. V120 centimeters </span>

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 6 rows of the same length, he has 3 chairs left ov

tresset_1 [31]

If he has 9 rows of equal length there are 3 chairs left over.

If he has 7 rows of same length there are 19 left over.

It's important to note that these two setups have the same number of chairs. So we can make an equation out of it.

9x + 3 = 7x +19

2x + 3 = 19

2x = 16

x = 8

So, x (8) is the number of chairs in each row with these setups.

Plug 8 into one of the equations and you will find how many chairs total there are.

9(8) + 3 = 75

There are 75 chairs total

How many meters are there in 234 cm?

Reika [66]

There are 100 cm for every 1 meter
$\frac{1 m}{100 cm}$
so insert the 234 as the numerator and simplify
$\frac{234cm}{100cm}$
The simplified form of the equation is 2.34
There is 2.34 meters in 234 cm

Y-4=0 in standard form

wolverine [178]

Standard form : Ax + By = C

y - 4 = 0
y = 4...this is a horizontal line and a horizontal line has a 0 slope

so in standard form, ur equation is : 0x + y = 4
