Answer:
2(x+6)(x-3)
Step-by-step explanation:
Factor the GCF out of the trinomial on the left side of the equation.
Greatest common factor of 2, 6, 18 is 2
so GCF is 2
divide each term when we take out GCF 2
so 
now factor the trinomial
product is -18 and sum is +3
6 times -3 is -18 and 6-3=3
Answer:
each side 5
Step-by-step explanation:
with 2 equal internal base angles, we know this is an isosceles triangle
this being isosceles also tells us that the 2 opposite sides are also equal
Therefore: x + 2 = 3x - 4
solving for x
x - 3x = -4 -2
-2x = -6
x = -6 ÷ -2
× = 3
substituting x:
x +2 = 3 + 2 = 5
3x-4 = 9 - 4 = 5
Answer: <span>275,365 cm³
</span>
Explanation:
Volume of the water = (3.14)(30)²(100) - 4/3(3.14)(12)³ = 275,365 cm³
The Wise Orange knows that volume of a cylinder = πr²h and a sphere is 4/3πr³
So first you would want to multiply 84 by 2 because that would let you know how many inches you are using right now. 84 x2 = 168 now that you know you are already using 168 inches you must subtract that from 300 to find out how much you have left 168 - 300 = 132 you now have to divide that by 2 to get how long one side is 132 divided by 2 is 66. She can make it 66 inches wide.
12)
well, the picture has a length of (x + 2.5) and a width of (x).
if we extend the picture 1 inch on all sides, it'll end up like the picture below.
13)
let's find the area of the larger rectangle, that includes the smaller rectangle, and then let's find the area of the smaller rectangle, and after <u>subtracting the smaller area from the larger area</u>, what's leftover is the shaded region.
14)
we'll do the same thing here as we did in 13)
