Answer:
Step-by-step explanation:
Each of the squares has trinomials that factor. x^2 - 14x + 49 = (x - 7)^2
When you take the square root (to get the side length) you get x - 7. So the length of each square is x - 7) = 0;..........x=7 That's the answer to a.
The answer to b is the same. The width =7
It's a square both sides have to be equal.
The length of the rectangle when the two squares are put together is 7 +7 = 14.
Answer: Question a = 7..... Question b = 7 ......... Question C = 14

Answer:
-1.75
Step-by-step explanation:
We know that the midpoint formula is [for the x-coordinate per say] x = 1/2x1 + 1/2x2. If we want to find a point that lies 1/4th of the way we use x = 3/4x1 + 1/4x1. How? Because the point lies 1/4th from one endpoint and 3/4th from the other.
x = 3/4x1 + 1/4x2,
x = 3/4(-3) + 1/4(2) = -9/4 + 2/4 = -7/4
= - 1.75
--- There is an easier way to do it though, but it is really vague so you should not use it. We can form a triangle with MN being the hypotenuse. What would the length of the legs be? They would be 6 and 5. Now let's form a triangle 1/4th of that. 6/4 = 1.5 and 5/4 = 1.25. If you look at the diagram, start from point N move up 1.5 units and over 1.25 forming our mini triangle. You can see the x-axis has a value of -1.75.
A company makes steel rods shaped like cylinders. Each rod has a radius of 2 centimeters and height of 70 centimeters. How much steel will the company need to make 243 rods? Use 3.14 for pie, and round your answer to one decimal
Answer:
213,645.6cm³
Step-by-step explanation:
Area of a cylinder is expressed as;
V = πr²h
r is the radius = 2cm
h is the height = 70cm
Get the volume of one rod;
V = πr²h
V = (3.14)(2)²(70)
V = (3.14)(4)(70)
V = 879.2cm³
one steel = 879.2cm³
243 rods = x
Cross multiply;
x = 879.2 * 243
x = 213,645.6
The company will need 213,645.6cm³ volume of steel to make 243 rods

Consider the triangle (in which angle4 is present)
by angle sum property,
20 + 40 + angle4 = 180
60 + angle4 = 180
angle4 = 180 - 60
angle4 = 120
Also,
angle2 = 120 (vertically opposite angles)
angle1 + angle2 = 180 (linear pair)
angle1 + 120 = 180
angle1 = 180 - 120
angle1 = 60

The coefficient of {q} in the sum of the given expressions is 7.
What is expression?A mathematical expression is a combination of terms both constants and variables. For example, we can write -
2x + 3y + 5
4x + 5
Given are the expressions as -
(23q – 34) and (–16q – r)
We can write the sum of the given expressions as -
(23q – 34) + (–16q – r)
(23q - 16q) - r - 34
7q - r - 34
Here -
(7)q - r - 34
(7) is the coefficient of {q}.
Therefore, the coefficient of {q} in the sum of the given expressions is 7.

Your family goes out for dinner on Sunday night. If the total bill came out to $175 but your parents had a 20% off coupon. How much will the entire meal cost if you also must pay 8% sales tax and a 18% tip?
Answer:
Step-by-step explanation:
175-20%= 35 off
175-35=140
140*8% tax= 11.20 tax
140+11.20= 151.20
151.20*18% tip= 27.216
151.20+27.22=178.42 total

The Dubois family has $5000 set aside for an upcoming vacation in the family plans to spend 1/4 of this amount on gasoline for the drive and motel rooms along the way and 1/2 of the remainder on meals how much does the Dubois family spend on meal
Answer:
$1875
Step-by-step explanation:
Money available with Dubois family = $5000
Money to be spent on gasoline and motel room = [tex]\frac{1}{4}[/tex] of the total amount
Therefore,
Money to be spent on gasoline and motel room = [tex]\frac{1}{4} \times 5000 = \$1250[/tex]
Remaining amount of money = Total amount - Money spent on gasoline and motel room
Remaining amount of money = $5000 - $1250 = $3750
As per question statement:
Half of the remaining money is to be spent on meals.
i.e. Money to be spent on meals = [tex]\frac{1}{2}\times \$3750 = \bold{\$1875}[/tex]
Therefore, the answer is:
$1875
a rectangle has vertices (0,0), (2k,0) and (0,k) find the fourth vertex
If a rectangle has vertices (0,0), (2k,0), and (0,k) the fourth vertex will be (4,8).
What is a rectangle?It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is given that the rectangle has vertices (0,0), (2k,0), and (0,k).
A(0,0)
B(2k,0)
C(0,k)
D(x,y)
Since the opposite of the rectangle is the same it will be opposite to one of the coordinates shown in the graph.
To uniquely identify points on a plane, use ordered pairs and the rectangular coordinate system (x,y). Pairs that are ordered show position in relation to the origin.
The x-coordinate shows the left and right sides of the origin. Y-coordinate positions are above or below the origin.
Thus, if a rectangle has vertices (0,0), (2k,0), and (0,k) the fourth vertex will be (4,8).

We move all terms to the left:
2(k-5)+3k-(k+6k)=0
We add all the numbers together, and all the variables
2(k-5)+3k-(+7k)=0
We add all the numbers together, and all the variables
3k+2(k-5)-(+7k)=0
We multiply parentheses
3k+2k-(+7k)-10=0
We get rid of parentheses
3k+2k-7k-10=0
We add all the numbers together, and all the variables
-2k-10=0
We move all terms containing k to the left, all other terms to the right
