-18x
you first times the numbers, which becomes -18
Next you add the exponent from the veriables (x) (if you're diving you're subtractiong example: x^a/x^b = x^a-b)
Sooo when you add them you get 8-7=1 which means.. x^1 (but you don't need to put the 1)
-18x
Answer: Select the first one
Step-by-step explanation:
-6 multiplied 3 is -18
AND they both have power x which means -6x⁸ multiply 3x ⁻⁷
= -18 x⁸ ⁺⁽⁻⁷ ⁾(As the have same variable )
= -18 x⁸⁻⁷
=-18 x

quadrilateral kstu has vertices at (7,0) (4,-6) (0,-2) and (0,0). rotate 180 degrees around the origin
Step-by-step explanation:
so basically for this on u have to draw this on graph every first number of the coordinate is on x axis e.g . (7,0) 7 is on x axis and 0 is on Y axis. you can use tracing paper for this which will be more helpful as u can trace the shape and move it half way.
As u rotate it around the origin so u just turn it half way. eg I drawn it on the picture.
hope this make sense :)

On the southeast corner of Millennium Park, there is a garden walk. It is marked off in red in the drawing below. Side C, the hypotenuse of the triangle, shows the row along which flowers will be planted.
(a) If side a measures 90 feet and side b measures 120 feet, how many feet of flowers will be planted along side c, the hypotenuse of the triangle? Show your work and explain your reasoning.
(b) Calculate the area of the red triangle to find the area of the garden. Show your work.
(C) Millennium Park has an outdoor concert theater. Before a concert, the area reserved for special seating is roped off in the shape of a triangle as shown below. How can the converse of the Pythagorean theorem help you determine whether the roped off area is in the shape of a right triangle?
Part B: The second link is for this part!!!!
(d) The front of the stage, side C, is 50 feet long. A 40-foot rope runs along the side of square B. A 30-foot rope runs along the side of square A. Is the roped off area, triangle ABC, a right triangle? Explain.
(e) The diagonal of square A, marked off by the red stars, is where the concession stand is located. A local high school band is performing at the outdoor theater on a summer evening. The band has a school banner that is 40-feet long, and band members would like to hang it across the concession stand to let people know they are performing. Estimate the length of the concession stand to determine if the school banner can fit across the length of the concession stand. Show your work and explain your reasoning.
Answer:
a^2 + b^2 = c^2...a and b are the legs and c is the hypotenuse
90^2 + 120^2 = c^2
8100 + 14400 = c^2
22500 = c^2.....take the sq rt of both sides...this gets rid of the ^2
sq rt 22500 = c
150 = c
so side a = 90 ft, side b = 120 ft, and side c = 150 ft
this is called the pythagorean theorem and it only works on right triangles

Dr Leonard Bernstein owner of software solving inc determines that he must mark up the software he sell to clients by 60% of selling price. Leonard's costs for a project with the local bank will total $1200000. What selling price should Leonard put in the contract with the bank
Answer:
The right solution is "$1,920,000".
Step-by-step explanation:
Given:
Project cost,
= $1200000
Dr. Leonard sells by
= 60%,
The mark up value will be:
= [tex]\frac{1200000\times 60}{100}[/tex]
= [tex]720,000[/tex] ($)
hence,
The selling price he should put with the bank will be:
= [tex]Project \ cost+Mark \ up \ value[/tex]
= [tex]1200000+720000[/tex]
= [tex]1,920,000[/tex] ($)

Step-by-step explanation:
The number of people who live in a unit of area is called the population density of the area. It usually given as people "per square mile" or "per square kilometer".
A map of the Orchard Hill Neighborhood is shown. The population of the Orchard Hill Neighborhood is 360 people. The lenght of each block is the same and the lenght of 20 blocks is 1 mile.
What is the area in square miles of Orchard Hill?
A. 0.35 square mile
B. 0.03 square mile
C. 0.15 square mile
D. 0.60 square mile
Answer: 0.03
Step-by-step explanation:
1 block = 1/20 mile = 0.05 miles
4(0.05) = 0.20
3(0.05) = 0.15
A=l•w=0.20(0.15)=0.03
The area of the Orchard Hill is 0.03 square miles if the length of each block is the same and the length of 20 blocks is 1 mile, option (A) is correct.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
We have:
20 blocks = 1 mile
1 block = 1/20 miles = 0.05 miles
Length of 3 blocks = 3×0.05 = 0.15 miles
Length of 4 blocks = 4×0.05 = 0.20 miles
Area of the Orchard Hill = 0.15×0.20 = 0.03 square miles
Thus, the area of the Orchard Hill is 0.03 square miles if the length of each block is the same and the length of 20 blocks is 1 mile, option (A) is correct.
