Answer:
x = -11
Step-by-step explanation:
5x + 2 = 4x - 9
-2 -2
5x = 4x - 11
-4x -4x
x = -11
Answer:
∠3 = 55° {being vertically opposite angles}
∠7 = ∠3 = 55° {being corresponding angles}
You are given two sides and an angle.
Using SAS, would use the law of cosines.
a = √(10^2 + 11^2 - 2*10*11*cos(43))
a = 7.75
Round to 7.8
Ratio means proportion, correlation, or relationship.
Eg. The ratio of brown dogs to white dogs is 6:2. This means there are 6 brown dogs and two white dogs in the group. You could also say that there are 3 times as many brown dogs as white dogs.
You can simplify a ratio. Take the example we looked at: 6:2. You could simplify that one by dividing each by the same number.
You would divide it by 2, and end up with 3:1. That still says that there are 3 times as many brown dogs as white dogs.
I hope this helps you.
Lets assume height as x
so width will be 2x
and length will be 3x similarly.
so,
Volume of prism = w * h * l
384 = 2x * x * 3x
384 = 6x^3
dividing both sides by 6
64 = x^3 ( taking cube root of 64)
4 = x
So,
Height = 4
width = 4 * 2 = 8
length = 4 * 3 = 12
Hope this helps.. :)
