Seven and seven eighths rounds up to eight. Two and eleven twelfths rounds to three. Estimate equation: 8+3=11. Now you know your answer should be around 11. Then to find your actual answer you have to find the common denominator! If u need anymore help ask me! Hope I helped!
Use distributive property
4(x-3) = 4x-12
2x-6 + 4x - 12
Combine like term
6x - 18

How to Solve!-
Repeat this distance formula for each side
Hey there! :)
In order to the find the missing side length of this triangle, we'll need to use the Pythagorean Theorem!
That equation is : a² + b² = c²
a = adjacent side
b = long side of rectangle
c = hypotenuse
We're already given the values of both a & c, so let's plug everything in!
a² + b² = c² → a = 10 , b = ? , c = 20
(10²) + b² = (20²)
Simplify.
100 + b² = 400
Subtract 100 from both sides.
b² = 400 - 100
Simplify.
b² = 300
Get the square root of b² & 300.
Simplify!
b = 17.3
So, the missing side length is the first answer choice : 17.3~Hope I helped!~
