Jane final solution is wrong due to the direction of the inequality sign
<h3>Solving linear equation</h3>
Linear equations are equation that has a leading degree of 1
Given the inequality below
-8x + 12x + 2 ≥ 62
Simplify to have
4x + 2 ≥ 62
Subtract 2 from both sides
4x + 2 - 2≥ 62 - 2
4x ≥ 60
Divide both sides by 4
4x/4≥ 60/4
x≥ 15
We can see that jane final solution is wrong due to the direction of the inequality sign

A combination is a selection of part from a set of objects. In a combination the order of selecting object does not matters.
So we use combination for selecting 3 from the population of 10
We know combination of selecting 'r' objects from 'n' is nCr
We need to find 10C 3
= 120
120 different samples of size 3 can be taken from a finite population of size 10
Answer:
After expanding the polynomial we get
Step-by-step explanation:
We need to expand the polynomial
Multiply the terms:
So, after expanding the polynomial we get
Volume of a cylinder = pi r^2 h where r = radius of the base and h = the height.
so if we are given a radius of 2 cm and a volume of 180 cm^3 we work out the height as follows:-
180 = pi * 2^2 * h
h = 180 / (pi*2^2)
height h = 180 / 4pi = 14.32 cm to nearest hundredth
Answer:
8.4cm
Step-by-step explanation:
we have to apply the pythagorean theorem and we will get that x^2=11^2-7^2
x^=121-49=72
x=sqrt72=8.4
