Please help me do question 21, 22 and 23. I am in 6th grade.

1 answer:

6 0

Question 21: 24 minutes

$\frac{3}{\frac{3}{2} } = \frac{x}{12}$

x = $(\frac{3}{\frac{3}{2} })(12)$

x = 24

Question 22: 20 centimeters

x = one side of the square

x² = 25

x = 5

4x = perimeter

4(5) = perimeter

20 = perimeter

Question 23: 17 sides

Hexagon = 6 sides

Octagon = 8 sides

Triangle = 3 sides

Total amount of sides = 6 + 8 + 3

Total amount of sides = 17

<h3>What Long division method?</h3>

Long division is a method for dividing one large multi digit number into another large multi digit number.

Given:

f(x)= x²+2x+1

g(x)= x+1

The steps to divide the polynomial is :

Divide the leading term of the dividend by the leading term of the divisor: x²/x=x.
Multiply it by the divisor: x(x+1)=x²+x.
Subtract the dividend from the obtained result: (x²+2x+1)−(x²+x)=x+1.
Divide the leading term of the obtained remainder by the leading term of the divisor: x/x=1.
Multiply it by the divisor: 1(x+1)=x+1.
Subtract the remainder from the obtained result: (x+1)−(x+1)
