Answer:

w^2-20w -100

Step-by-step explanation:

(w+10)(w-10)

Foil

first : w*w = w^2

outer: w*-10 = -10w

Inner: 10*w = 10w

last: -10 *10 = -100

Add them together

w^2 -10w-10w -100

Combine like terms

w^2-20w -100

Type the correct answer in each box. Use numerals instead of words.
DedPeter [7]

Answer:

c = 7

d = 5

Step-by-step explanation:

combining coefficient a with the nth root of b: a√ⁿb = √ⁿ((a)ⁿb). This is the reverse of simplifying a radical.

8x³√²7x = √²((8x³)²)√²(7x) = √²(64x⁶)√²(7x) = √²((64x⁶)(7x)) = √²((64 × 7)(x⁶ × x)) = √²((448)(x⁷)) = √²448x⁷ →

√²448x⁷ = √²448xᶜ.

7 → c, √²448x⁷ = √²448x⁷, c = 7.

4x√³9x² = √³((4x)³)√³(9x²) = √³(64x³)√³(9x²) =

√³((64x³)(9x²)) = √³((64 × 9)(x³ × x²)) = √³((576)(x⁵)) = √³576x⁵ →

√³576x⁵ = √³576xᵈ.

5 → d, √³576x⁵ = √³576x⁵, d = 5.

Subtract 3 1/3 from each side

6-3 1/3>x+3 1/3-3 1/3

Replace 6 with 5 3/3

5 3/3 - 3 1/3 > x
