Answer:
(-5 , 0) and (6 , 0)
Step-by-step explanation:
In order to get the coordinates of the x-intercept(s) of the graph of y=(x-6)(x+5)
we need to solve for x the equation (x-6)(x+5) = 0
(x-6)(x+5) = 0
⇌
x - 6 = 0 or x + 5 = 0
⇌
x = 6 or x = -5
therefore
the coordinates are :
(-5 , 0) and (6 , 0)

Find the point that lies on the line described by the equation below. y - 8 = - 3 (x-6)
Answer:
B. (6, 8)
Step-by-step explanation:
To figure this out, you can plug in the coordinates to see if you get matching answers. Since you believe answer "B," is correct, we can check:
y - 8 = -3(x - 6)
8 - 8 = -3(6 - 6)
0 = -3(0)
0 = 0
Since the answers match, that makes answer "B," correct.

The spinner to the right is spun 20 times. It lands on red 6 times, yellow 2 times, green 8 times, and blue 4 times.
Based on the data, what is the experimental probability of landing on yellow?
You may give your answer as a simplified fraction, decimal, or percent.
Answer:
0.1
Step-by-step explanation:
Given: The spinner lands on red 6 times, yellow 2 times, green 8 times, and blue 4 times. when it is spun 20 times.
To find: experimental probability of landing on yellow
Solution:
Probability refers to chances of occurring of some event.
Probability = number of favourable outcomes total number of outcomes
As the spinner lands on yellow 2 times,
number of favourable outcomes = 2
Total number of outcomes = 20
Probability = 2/20 = 1/10 =0.1
The volume of a ball is 288pi cm cubed. Find the dimensions of a rectangular box that is just large enough to hold the ball.
Answer:

Step-by-step explanation:
The volume of a sphere is 288 pi cm tripled . Find the lenght of a radius of a SPHERE.What is the answer and how did you do it?
-------------------
The volume of a sphere of radius r is:
V+=+4%2Api%2Ar%5E3%2F3
It's r cubed, not tripled. meaning r*r*r
-------------------
288pi+=+4%2Api%2Ar%5E3%2F3

Answer:
A=238.87 cm
Step-by-step explanation:
First find the area for the rectangle
11*23= 253 cm
then find the area for the little circles
D=3cm so r=1.5cm
Now plug in values into formula
A=π(1.5)^2
A=π(2.25)
A=3.14(2.25)=7.065cm
A=7.065cm since there are two circles
7.065*2=14.13
Now subtract the area of the circles from the rectangle
253-14.13=238.87

A rectangular building has a perimeter of 208 meters. It’s area is 2415 square meters. What are the dimensions of the building?
Answer:
Step-by-step explanation:
Perimeter of rectangle = 208 m
2*(l + w) = 208 {divide both sides by 2}
l +w = 208/2
l +w = 104
l = 104 - w
Area of rectangle = 2415 square meters
l*w = 2415
Substitute l = 104 - w in the above equation,
(104 - w ) *w = 2415
104w - w² = 2415
0 = 2415 - 104w + w²
w² - 104w + 2415 = 0
Sum = -104
Product = 2415
Factors = (-69) , (-35)
w² - 35w - 69w + (-69)*(-35) = 0
w(w - 35) - 69(w - 35) = 0
(w -35)(w -69)
w - 35 = 0 ; w -69 = 0
w = 35 ; w = 69
The dimensions of the building: 35 , 69

What is a polynomial?Polynomial is an equation written with terms of the form kx^n.
where k and n are positive integers.
There are quadratic polynomials and cubic polynomials.
Example:
2x³ + 4x² + 4x + 9 is a cubic polynomial.
4x² + 7x + 8 is a quadratic polynomial.
We have,
We can factor the polynomial 2x² (x - 5) - 3(x - 5) by first factoring out the common factor of (x - 5).
This gives:
2x² (x - 5) - 3(x - 5)
= (x - 5)(2x^2 - 3)
Thus,
The factor of the polynomial is (x - 5)(2x² - 3).

Check that x=2 and y=5 is a solution of both equations below:
X+2y=12
3x+6y=36 *
Answer:
yes
Step-by-step explanation:
Substitute x = 2 and y = 5 into the left side of the equations and if equal to the right side then they are a solution.
x + 2y = 2 + 2(5) = 2 + 10 = 12 ← True
3x + 6y = 3(2) + 6(5) = 6 + 30 = 36 ← True
Thus x = 2, y = 5 is a solution to both equations

Answer:
3600
Step-by-step explanation:so it is easiest to do one persons costs then just multiply it by 4 to get the cost of 4 people. so first for one person..... (their travel is) 130 + (hotel x 7 days) 60 x 7 + (spending money) 350 =900 . now multiply this by 4 = 3600
Let's start off by working out the cost for one person. This person has to spend 130 pounds on travel and have 350 pounds of spending money. So far that is 130+350 = 480 pounds. Then it says the hotel costs 60 pounds per day. At 7 days, it will cost one person 7*60 = 420 pounds. This adds onto the 480 to get 420+480 = 900.
Therefore, each person will need 900 pounds to go on a 7 day trip. If we had 4 people going, then 4*900 = 3600 pounds is needed total.
Answer: £3600This strip is 12 cm long Find the length of 25% of the strip
Answer:
If the strip is 12cm and it is asking for 25% of it, you can divide 12 by 4, as 25 is 1/4 of 100.
The answer will be 3cm
Answer:
3
Step-by-step explanation:
Twenty five percent of the 12 cm strip means 25÷ 100 = 0.25 .
so 0.25 x 12 = 3.
