Use the distributive property to write an expression equivalent to 5x (3+4)
Law Incorporation [45]
You can solve it algebraically by simply adding the numbers in the parenthesis and multiplying to get 35x but if you want to solve it using distributive property exclusively then distribute as so

5x(3) + 5x(4)

15x + 20x

35x

Evaluate the integral x^3 (x 4 −8)^44 dx by making the substitution u = x^4 - 8
Eduardwww [97]

Answer:

(x^4-8)^45 /180 +c

Step-by-step explanation:

If u=x^4-8, then du=(4x^3-0)dx or du=4x^3 dx by power and constant rule.

If du=4x^3 dx, then du/4=x^3 dx. I just divided both sides by 4.

Now we are ready to make substitutions into our integral.

Int(x^3 (x^4-8)^44 dx)

Int(((x^4-8)^44 x^3 dx)

Int(u^44 du/4)

1/4 Int(u^44 dul

1/4 × (u^45 / 45 )+c

Put back in terms of x:

1/4 × (x^4-8)^45/45 +c

We could multiply those fractions

(x^4-8)^45 /180 +c

Find the volume of a cube that will hold sixty-four 4.19 in3 toy bouncy balls. (round to nearest whole number)
nadya68 [22]
Volume of the toy bouncy ball:
V = 4/3 r³ π
4.19 = 4/3 r³ · 3.14
r³ = ( 4.19 · 3 ) : ( 4 · 3.14 ) = 1
r = ∛1 = 1 in
Volume of the cube: V = a³
There are 64 toy balls. It means that there are 4 x 4 x 4 in the cube.
a = 4 · 2 r = 8 in
V = 8³ = 8 · 8 · 8 = 512 in³
Answer: B ) 512 in³
