I'm assuming that x 8 = x⁸ and 3x 5 = 3x⁵.
So let's solve.
x⁸ + 3x⁵ = x⁵(____)
x⁸ + 3x⁵ = x⁵(x³ __)
x⁸ + 3x⁵ = x⁵(x³ + 3)
Therefore the missing expression is (x³ + 3)

Answer:
(1 - 4x)³
Step-by-step explanation:
The first 2 terms are a difference of cubes and factor in general as
a³ - b³ = (a - b)(a² + ab + b²), thus
1 - 64x³
= 1³ - (4x)³
= (1 - 4x)(1 + 4x + 16x²)
Thus
1 - 64x³ + 48x² - 12x ← factor out 12x from each of the 2 terms
= (1 - 4x)(1 + 4x + 16x²) + 12x(4x - 1) ← factor out - 1 from (4x - 1)
= (1 - 4x)(1 + 4x + 16x²) - 12x(1 - 4x) ← factor out (1 - 4x) from the terms
= (1 - 4x)(1 + 4x + 16x² - 12x)
= (1 - 4x)(1 - 8x + 16x²) ← perfect square
= (1 - 4x)(1 - 4x)²
= (1 - 4x)³ ← in factored form
B) ABCD is a rhombus as all the sides are congruent (equal)
Answer:
x=-6
Step-by-step explanation:
7x-9x=6+6
-2x=12
x=-6
Hello!
To find out if this food is enough we will add together all of the prices and multiply it by three to see if it is enough.
3(4.89+5+8.49)=55.14
Yes! They will have enough money with $4.86 to spare!
I hope this helps!
