A boy purchased​ (bought) a​ party-length sandwich 54 in. long. He wants to cut it into three pieces so that the middle piece is
iren2701 [21]

Answer:

length of shortest piece = 13 in

length of middle piece =  19 in

length of longest piece =  22 in

Step-by-step explanation:

Total length of sandwich = 54 inch

Let shortest piece = x

Middle piece = x+6

Longest piece = x+9

Add this pieces will make complete sandwich

x+(x+6)+(x+9) = 54

Solving

x+x+6+x+9 = 54

Combining like terms

x+x+x+6+9 = 54

3x + 15 = 54

3x = 54 -15

3x = 39

x = 13

So, length of shortest piece = x = 13 in

length of middle piece = x+6 = 13+6 = 19 in

length of longest piece = x+9 = 13+9 = 22 in

similar; RYL by SAS similarity

Step-by-step explanation:

Side RL Is congruent to side RH and side RY is congruent to side RA by a scale factor of 3.5. and we know thank angles LRY and HRA are congruent by the reflexive property. So the two triangles are congruent by Side-Angle-Side similarity.

Which function is a quadratic function? u(x) = –x 3x2 – 8 v(x) = 2x2 8x3 9x y(x) = x2 3x5 4 z(x) = 7x2 2x3 – 3.
Komok [63]

The function u(x)=-x+3x^{2} -8 is a quadratic function due to the highest exponent being 2.

Given functions are:

u(x)=-x+3x^{2} -8

v(x)=2x^{2} +8x^3+9x

y(x)=x^{2} +3x^5+4

z(x) =7x^{2} +2x^3-3

<h3>What is a quadratic function?</h3>

A function of the form f(x)=ax^{2} +bx+c with a\neq 0 is called a quadratic function means the highest exponent of polynomial should be 2.

Let us check one by one.

u(x)=-x+3x^{2} -8

Highest exponent =2

The function is also of form f(x)=ax^{2} +bx+c so u(x) is a quadratic function.

The functions v(x), y(x), and z(x) are having highest exponents as 3,5, and 3 respectively so they are not quadratic functions.

Hence, the function u(x)=-x+3x^{2} -8 is a quadratic function due to the highest exponent being 2.
