Points J and K are midpoints of the sides of triangle FGH.
Triangle F G H is cut by lines segment J K. Point J is the midpoint of side G H. Point K is the midpoint of side H F. Line segments G J and J H are congruent. Line segments H K and K F are congruent. The Length of J K is 2 y + 5 and the length of G F is 5 y + 3.

Answer:
C. 7
Step-by-step explanation:
Points J and K are midpoints of the sides of triangle FGH.
=> JK = 1/2FG
2y + 5 = 1/2(5y + 3)
4y + 10 = 5y + 3
5y - 4y = 10 - 3
y = 7
The value of y is 7 for the given triangle.
What are the properties of Triangle?The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
We know that GJ = JH, and HK = KF.
Also, J and K are midpoints of GH and HF, respectively.
Therefore, we can say that:
GJ + JH + HK + KF = GF
2(GJ + HK) = GF
2(2y + 5) = 5y + 3
4y + 10 = 5y + 3
y = 7
Therefore, the value of y is 7.

What is Euclid's division lemma?
Euclid's division lemma states that for any positive integers, let's say a and b the condition [tex]\rm a=bq+r[/tex], where [tex]\rm 0\leq r\leq b[/tex].
Mathematically, we can say that
Dividend = divisor × quotient + remainder
P(x) = g(x) × q(x) + r(x)
To find the divisor g(x)
[tex]x^{4} -3x^{2} +4x-3= \rm g(x)\times (x^{2} +x-3) + r(x)\\[/tex]
On dividing P(x) by q(x) we get,
[tex]x^{4} -3x^{2} +4x-3 \div (x^{2} +x-3) = \rm g(x)+0[/tex][tex](x^{2} +x-3) \times (x^{2} +x-1)\div (x^{2} +x-3) = \rm g(x)\\(x^{2} +x-1) = \rm g(x)\\[/tex]
Hence, the polynomials [tex](x^{2} +x-1)[/tex] and [tex](x^{4} -3x^{2} +4x-3)[/tex] has a quotient of [tex](x^{2} +x-3)[/tex]. The polynomial is [tex](x^{2} +x-1)[/tex].

thanks
Answer:
y = 6
Step-by-step explanation:
- x + 3y = 9 ( add x to both sides )
3y = 9 + x → (1)
y = [tex]\frac{2}{3}[/tex] x ( multiply both sides by 3 to clear the fraction )
3y = 2x → (2)
substitute 3y = 2x into (1)
2x = 9 + x ( subtract x from both sides )
x = 9
substitute x = 9 into (1)
3y = 9 + 9 = 18 ( divide both sides by 3 )
y = 6
Solve for x and y.

Approximately 5.6 x 10¹⁴ grains of wheat in scientific notation.
Describe Geometric Series?A geometric series is a sequence of numbers in which each term is obtained by multiplying the previous term by a fixed constant. This constant is called the common ratio, and it is denoted by the letter "r".
The formula for the sum of the first n terms of a geometric series is:
S_n = a(1 - rⁿ)/(1 - r)
where S_n is the sum of the first n terms, a is the first term of the sequence, r is the common ratio, and n is the number of terms in the series.
The number of grains of wheat on each square of the board can be found by raising 2 to the power of the square number minus 1. For example, the number of grains of wheat on the first square is 2⁰ = 1, the number on the second square is 2¹ = 2, the number on the third square is 2² = 4, and so on.
So, the total number of grains of wheat on the board is the sum of 2⁰ + 2¹ + 2² + ... + 2⁴⁸. This is a geometric series with first term 1 and common ratio 2. Using the formula for the sum of a geometric series, the total number of grains of wheat is:
2⁰ + 2¹ + 2² + ... + 2⁴⁸ = (2⁴⁹ - 1)/(2 - 1) = 2⁴⁹ - 1
This is approximately 5.6 x 10¹⁴ grains of wheat in scientific notation.

Mr. Kim randomly divides his class into groups. Each group has 5 students and each group is randomly assigned 1 of 6 projects to do. Which simulation best models the outcomes of the sets up?
A rolling 2 number cubes, each with the numbers 1-6 on it
B. spinning a spinner divided into 5 equal sections, and flipping a coin 3 times
C.flipping a coin 5 times, and spinning a spinner divided into 6 equal sections
D. drawing 1 of 5 numbered papers out of a bag, and rolling a number cube with the numbers 1-6 on it one time
Answer:
D
Step-by-step explanation:
Because neither Mr. Kim nor anyone else is picking the people of a specific group when the paper is drawn from the bag. And rolling a cube with numbers 1-6 you almost never get the number you want so it is really random. And then after the groups are picked they roll the die and then that number is crossed off so it is not used again with the other groups.
