To multiply it by itself three time eg 2x2x2
Answer:10x^2 -18
Step-by-step explanation:since f(x) is becoming the new x then youd subtitute the equation into the x of the g(x) equation. which would be 5(2x^2 -5) +7 which is 10x^2 -25 +7.and you'd simplify from there.
Answer:
x = 1
Step-by-step explanation:
Step 1: Write equation
9 - 2x = 7x
Step 2: Solve for <em>x</em>
<u>Add 2x on both sides:</u> 9 = 9x
<u>Divide both sides by 9:</u> x = 1
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9 - 2(1) = 7(1)
9 - 2 = 7
7 = 7
Range
Because it has the biggest difference between the two sets (14 in set 1 and 57 in set 2) so the outlier (the value 63 in set 2) affected it the most
Euler's formula for a polyhedron is given by:

Make E, the subject of the formula:

Put F = 20, V = 12, to obtain E,

Therefore, there are 30 edges
