Answer:
The answer to your question is: 4x²y³
Step-by-step explanation:
Simplify ∛(-64x⁶y⁹)
First, find the prime factors of 64
64 2
32 2
16 2
8 2
4 2
2 2
1 then 64 = 2⁶
∛ (-2⁶x⁶y⁹)
Roots can be expressed as fractional powers where the numerator is the power of the number inside the root and the denominator is the root.
Ex. -2 ⁶/³ x⁶/³ y⁹/³
Now simplify
(-2)² x² y ³
Finally
4x²y³

Answer:
$96
Step-by-step explanation:
let the the amount each men pay when they were 8 be x
let the total amount for the boat rental be y
8x=y .....................equ1
if two men withdraw from the party, and the amount each men pay increases by $4 then;
(x+4)6 =y
6x+24=y ...........equ2
make x the subject of formula from equ1;
x=y/8
substitute x as y/8 into
6(y/8) +24 =y
3y/4 +24=y
24=y-(3y/4)

24=y/4
y=24*4
y=$96
Answer:

Step-by-step explanation:
→ We know that co-interior angles add up to 180°, so we can set up an equation
x + 17 + 4x + 3 = 180
→ Collect the x terms
5x + 17 + 3 = 180
→ Collect the integers
5x + 20 = 180
→ Minus 20 from both sides to isolate 5x
5x = 160
→ Divide both sides by 5 to isolate x
x = 32
⇒ Now we know the value of x, we can substitute it in back into m∠f because we know angles on a straight line add up to 180°
4x + 3 when x = 32 ⇔ 4 × 32 + 3 ⇔ 128 + 3 ⇔ 131
