Answer:
22x^2-9x+32
Step-by-step explanation:
(21x² - 6x +14) + (x²-3x+18)
To add, we need to combine like terms
21x^2+x^2 -6x-3x +14+18
22x^2-9x+32
If the whole diameter of sphere is 6 inch(means radius is 3 inch) & thickness of material is 1 inch, so the radius of the hollow part should be 2 inch (3-1=2)
The total volume of the ball will be;
= Total volume - Volume of hollow part
= 4/3πr³ - 4/3πr³
= 4/3 × 3.14 × (3)³ - 4/3×3.14×(2)³
= 4 × 3.14 × 9 - 4/3 × 3.14 × 8
= 113.04 - 33.52
= 79.52
If the density of the material is 3.25 g/in3, then the density of 79.52 inch³ should be;
= 79.52 × 3.25
= 258.44 g
Now, if there are 8 spheres in one box, the weight if box will be;
= 258.44 × 8
= 2,067.52 g

Complete the statement to describe the expression ab+cd+ef+ghab+cd+ef+gha, b, plus, c, d, plus, e, f, plus, g, h. The expression
solmaris [256]
Answer:
The expression contains FOUR terms and each term contains TWO factors.
Step-by-step explanation:
In algebra, the word term refers to single numbers(10), variables<em>(</em><em>y</em><em>)</em> also the product of the two(<em>10y</em>).
In the given expression : <em>ab+cd+ef+gh .</em>
We have four terms;
A factor is part of a product. For the given equation we Four terms each term will have two factors.
- <em>ab</em>- is a product of factor a and b
- <em>cd- </em>is a product of factor<em> c </em>and<em> d</em>
- <em>ef-</em>is a product of factor<em> e </em>and<em> f</em>
- <em>gh-</em>is a product of factor<em> g </em>and<em> h </em>
