b) [tex]25x^{4} y^{3} z+5x^{7}y^{8} +10x^{2}y^{4} z\\[/tex]
Let us verify,
a) Consider the trinomial [tex]35x^{2} y^{5}z^{2} +5 x^{4}y^{9}z +15x^{3} y^{3}[/tex],
The Greatest Common Factor of 35, 5, 15 is 5
The Greatest Common Factor of [tex]x^{2} ,x^{4} ,x^{3} =x^{2}[/tex]
The Greatest Common Factor of [tex]y^{5} ,y^{9} ,y^{3} = y^{3}[/tex]
There is no G.C.F for z because it is missing in the 3rd term.
So, the G.C.F of the trinomial [tex]35x^{2} y^{5}z^{2} +5 x^{4}y^{9}z +15x^{3} y^{3}[/tex] = [tex]5x^{2} y^{3}[/tex]

In an investigation, Detective Cortez discovered a photograph that showed his number one suspect at the scene of the crime. To get a better look, he enlarged the picture by a scale factor of 8/1. If the original photo measured 4 inches by 3.6 inches, what were the dimensions of the enlargement?
Answers
The dimensions of the enlargement will be: 32 inches by 28.8 inches.
How do we get the new dimensions?The new dimensions can be gotten with the formula below:
Scale factor = Dimensions of new image / Dimensions of the original image.
Dimensions of new image = Scale factor × Dimensions of the original image
8 × 4 = 32 inches
8 × 3.6 = 28.8 inches.

Yes, it is proportional because the ratios for miles per hour are all equivalent to 1.25 miles per hour.
Yes, it is proportional because the ratios for miles per hour are all equivalent to 0.8 miles per hour.
No, it is not proportional because 3.75 miles in 3 hours is not equivalent to 7.5 miles in 6 hours.
No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.
Answers
Answer:
No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.
Step-by-step explanation:
first lets find out how far they hiked per hour3.75 mi in 3 hourswe need to do 3.75÷3= and we get 1.25 mi an hour now we need to do the next oneit is 7.5 mi in 6 hoursso we are gonna do 7.5÷6=and we get 1.25 mi an hournow lets do the last one12 mi in 8 hourswe are gonna do 12÷9=and we get 1.5 mi in an hourso the 3 hours and 6 hour are proportional so it would be: No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.The correct relationship between the hikers distance and time is;
No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.
What is Proportional?
Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
A group of hikers tracked how long it took to hike a 20-mile trail.
And, They hiked 3.75 miles in 3 hours, 7.5 miles in 6 hours, and 12 miles in 8 hours.
Now,
Find the proportional as;
For hiked 3.75 miles in 3 hours,
Proportional = 3.75 / 3
= 1.25
For hiked 7.5 miles in 6 hours,
Proportional = 7.5 / 6
= 1.25
For hiked 12 miles in 8 hours,
Proportional = 12 / 8
= 1.5
Thus, The correct relationship between the hikers distance and time is;
No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

Depending on the length of their sides, triangles can be categorized as equilateral, isosceles, or scalene.
The three interior angles of a triangle will always have a sum of 180°. A triangle cannot have an individual angle measure of 180°, because then the other two angles would not exist (180°+0°+0°).

Given:
B = Midpoint = (6, 0)A = (x₁, y₁) = (3h+4, 1-2h)C = (x₂, y₂) = (k-3, k-2)Substitute the given values into the formula:
[tex]\implies (6, 0)=\left(\dfrac{k-3+3h+4}{2},\dfrac{k-2+1-2h}{2}\right)[/tex]
[tex]\implies (6, 0)=\left(\dfrac{k+3h+1}{2},\dfrac{k-2h-1}{2}\right)[/tex]
Equating the x-values to create an expression for k:

[tex]\implies k+3h+1=12[/tex]
[tex]\implies k+3h=11[/tex]
[tex]\implies k=11-3h[/tex]
Equating the y-values to create an expression for k:

[tex]\implies k-2h-1=0[/tex]
[tex]\implies k-2h=1[/tex]

What is Linear Programming?When the requirements of a mathematical model are represented by linear relationships, the best result can be obtained using a technique known as linear programming (LP), also known as linear optimization. A particular type of mathematical programming is linear programming. Formally speaking, linear programming is a method for optimising a linear objective function under the constraints of linear equality as well as linear inequality. Convex polytopes, a set defined as that of the intersection of a finite number of half spaces, which are defined by a linear inequality, make up its feasible region. A real-valued affine (linear) function defined on the this polyhedron serves as its objective function. If there is a point in the polytope in which this function does have the smallest (or largest) value, a linear programming algorithm locates it.
Let the cost of 1 slice of pizza be x and cost of 1 soda be y.
Now,
Richard bought 3 slices of pizza and 2 sodas for $8.75
Therefore, [tex]3x+2y=8.75[/tex]
Jordan bought 2 slices of pizza and 4 sodas for $8.50
Therefore, [tex]2x+4y=8.50[/tex]
Solving above equations, we get [tex]x=2.25[/tex] and [tex]y= 1[/tex].
Cost of 1 slice of pizza and 3 sodas = 2.25 + 3*1
= 2.25 + 3
= 5.25
Hence, Cost of 1 slice of pizza and 3 sodas = $5.25
