6. Which of the following values are the zeroes of the expression 2x(x - 5)(x+7)?
(1) {-7,0,5)
(3) {-5, -2,7}
(2) {-7, -2,5)
(4) {-5,0,7}
Answer:
Step-by-step explanation:
To get the zeros of the expression 2x(x - 5)(x+7), we are going to equate the expression to zero and find the corresponding value of x as shown;
2x(x - 5)(x+7) = 0
2x = 0
x-5 = 0
x+7 = 0
From 2x = 0
x = 0/2
x = 0
From x-5 = 0
x = 0+5
x = 5
From the equation x+7 = 0
x = 0-7
x = -7
Hence the values of the zeros are {-7, 0, 5}
What does X equal.

2. I buy two bottles of cola for £1.40 each. How much change will I have from £5?
Answer:
£2.20
Step-by-step explanation:
ok i don't know any thing about pounds i think those are pounds but i do know my math
2 x 1.40 = 2.80
if you gave the caster 5 pounds they would give you ? back
5 - 2.80 = 2.20
you would get 2.20 pounds in return
Answer:
£2.20 (Without paying taxes)
Step-by-step explanation:
First you multiply 1.4 x 2 to get 2.8
Then subtract that by 5 ( 5.0 - 2.8)
Finally from that you will have gotten the answer 2.2
The sum of two numbers is 342. One of the numbers is 252. What is the other number?
Answer:
90
Step-by-step explanation:
342-252=90
So, therefore, 252+90=342
Answer:
90
Step-by-step explanation:
Since the sum is 342 and we already know the first number is 252 we would take away 252 from 342 to get the amount of the second number.
(342-252=90)
We got 90 and to check we would add 252+90 which is =
(252+90=342)
The answer is 90

80/36 as a mixed number
Answer:
yes because the one on top is larger than the number on the bottom
Answer:
2 2/9
Step-by-step explanation:
20/9 = 2 2/9
36 x 2 = 72
80 - 72 = 8/36
2 8/36 = 2 2/9
On which surface is the student unable to apply enough force to overcome the force of friction
Rough surfaces
Ex=carpet
The student unable to apply enough force to overcome the force of friction on rough surfaces.
What is Force?
A force is an influence that can change the motion of an object.
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
We need to find the type of surface the student unable to apply enough force to overcome the force of friction.
A rough surface will have more friction because on the rough surface there will be more irregularities.
So rough surface is the student unable to apply enough force to overcome the force of friction.
Hence, the student unable to apply enough force to overcome the force of friction on rough surfaces.

Simplify -3(x + 3) + 4x
Answer: x2 + 34x - 13
Step-by-step explanation:
STEP
1
Trying to factor by splitting the middle term
1.1 Factoring x2+34x-13
The first term is, x2 its coefficient is 1 .
The middle term is, +34x its coefficient is 34 .
The last term, "the constant", is -13
Step-1 : Multiply the coefficient of the first term by the constant 1 • -13 = -13
Step-2 : Find two factors of -13 whose sum equals the coefficient of the middle term, which is 34 .
-13 + 1 = -12
-1 + 13 = 12
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
x2 + 34x - 13
Bob, Sally, and Billy Bob Joe are sharing jelly beans. Bob started with 77 jelly beans, Sally started with 12 jelly beans, and Billy Bob Joe started with 19 jelly beans. Bob gave 45 jelly beans to Sally. Sally gave 29 jelly beans to Billy Bob Joe, and Billy Bob Joe ate 30 jelly beans. How many jelly beans does Billy Bob Joe have left?
Answer:
Billy Bob Joe now has 18 jelly beans left
Step-by-step explanation:
Bob initially has 77 jelly beans, Sally initially has 12 jelly beans and Billy Bob Joe initially has 19 jelly beans.
If Bob gives 45 jelly beans to Sally, Bob now has 77 - 45 = 32 jelly beans and Sally now has 12 + 45 = 57 jelly beans.
Sally now gives 29 jelly beans to Billy Bob Joe. Sally now has 57 - 29 = 28 jelly beans and Billy Bob Joe now has 19 + 29 = 48 jelly beans.
If Billy Bob Joe now eats 30 jelly beans, he now has 48 - 30 = 18 jelly beans.
So, after eating 30 jelly beans, Billy Bob Joe now has 18 jelly beans left.

Once a month, volunteers from the Green Sea Club clean up litter at the beach. Last month, the volunteers picked up 8 pounds of trash in 4 hours. This month, the same group of volunteers will spend 3 hours picking up trash.
If they pick up trash at the same rate, how many pounds of trash should the volunteers pick up this month?
Answer:
Step-by-step explanation:
8 pounds.... 4hours
x pounds.... 3 hours
x=3 ×8 :4
x=24 :4
x=6 pounds of trash
The number of pounds of trash should the volunteers pick up this month is 6.
Calculation of the number of pounds:Since Last month, the volunteers picked up 8 pounds of trash in 4 hours. This month, the same group of volunteers will spend 3 hours picking up trash.
So here we can do
x=3 ×8 :4
x=24 :4
x=6
Hence, The number of pounds of trash should the volunteers pick up this month is 6.

Suppose m∠3 = 128 and m∠6 = (10x + 8). What value of x would result in a || b?
A. 8.2
B. 4.4
C. 17.2
D. 12.0
Answer:
x = 12
Step-by-step explanation:
The attached figure shows the measures of the angles. Here, line a is parallel to line b.
Given that,
m∠3 = 128 and m∠6 = (10x + 8)
We need to find the value of x.
Here,
[tex]\angle 3 =\angle 6[/tex] (alternate interior angles)
So,
[tex]10x+8=128\\\\10x=128-8\\\\10x=120\\\\x=12[/tex]
So, the value of x is 12. Hence, the correct option is (D).

Find the cube root of 343a³b⁶
Answer:
[tex]7ab^{2}[/tex]
Step-by-step explanation:
You take the cube root of each piece of the term separately:
7 x 7 x 7 = 343, so the cube root of 343 = 7
a^3 = a x a x a, so the cube root of a^3 = a
b^6 = b x b x b x b x b x b = b^2 x b^2 x b^2, so the cube root of b^6 = b^2
