Answer: No the students work is not correct. Because you are using distribution. Which means that 3 has to multiply the y2 and 2 not just the y2! And after you distribute it you need to simplify!
Step-by-step explanation:
Answer:
(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6
Step-by-step explanation:
Given the expression
3-6y² and y²+2
We have to find the product of 3-6y² and y²+2
Clara's Solution:
(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2)
= 3y² – 12y²
= -9y²
NO!
The student's work is INCORRECT!
Clara did not imply the correct distribution of multiplying the terms in the first step.
Here is the correct solution:
(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2) + (3)(2) + (–6y²)(y²)
= 3y² – 12y² + 6 - 6y⁴
= - 6y⁴ - 9y² + 6
Therefore,
(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6

49/7 as a whole number
Answer:
Here i will simplify 49/7 to its simplest form and convert it to a mixed number if necessary.
In the fraction 49/7, 49 is the numerator and 7 is the denominator.
do this by first finding the greatest common factor of 49 and 7, which is 7.
Then, divide both 49 and 7 by the greatest common factor to get the following simplified fraction:
7/1
Therefore, this equation is true:
49/7 = 7/1
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.
7/1 = 7

The ratio of Rogers age to his sons is 7:3. If the sum of their ages are 60 how old is Rogers son
Answer:24
Step-by-step explanation:
Sum of their ages is 60 yr. As such
7x + 3x = 60
10x = 60
x = 60 / 10
x = 6
The rationale is 6, therefore
Father's age is 7x = 7 × 6= 42 years
Son's age is 3x = 3 × 6 = 18 years
Difference in their ages
42 - 18 = 24 years

What is the final elevation if a butterfly starts at 20 m and changes negative 16 m
Answer:
4 meters
Step-by-step explanation:
Given that :
Initial elevation of butterfly = 20 meter
Change in elevation from initial height = negative 16 m = - 16 meter
Final elevation can be obtained by taking the sum of initial elevation and the change in elevation
(20 m + (- 16 m))
(20 m - 16 m)
= 4 meters
Carl sees 25 melons at the store. 15 are small and the rest are large. How many melons are large?
Answer: 10 large melons
Step-by-step explanation:
Carl saw 25 melons at a store.
Of these 25, 15 were small and the rest were large.
The number of large melons will have to be the whole total of 25 melons less the number of small melons which is 15:
= 25 total melons - 15 small melons
= 10 large melons
a rectangles side lengths are 8 cm and 4 cm. Approximate the length of the diagonal of the rectangle to the nearest tenth.
Answer:
8.4cm
Step-by-step explanation:
first you have to square both sides
8²+4²= Hypotenuse (the diagonal)
you'll get
56 + 16
next you add it, and it'll equal 72
lastly you'll find the square root of that number
which is going to give you 8.4

True or false. A linear function always has an exponent of one or zero.
Answer:
False
Step-by-step explanation:
The graph of a linear function is a straight line. Graphically, where the line crosses the x -axis, is called a zero, or root. Algebraically, a zero is an x value at which the function of x is equal to 0 . Linear functions can have none, one, or infinitely many zeros.
Answer:
True.
Step-by-step explanation:
A linear function has the exponent of 0 or 1. A function with a degree of 2 would be quadratic and an exponent of 3 would be cubic.
A farmer owns a field with an area of 0.037 km2. The farmer buys another field with an area of 9600 m2. What is the total area of the fields he now owns in km2?
Answer:
0.0946km²
Step-by-step explanation
Area of the farmland owned = 0.037km²
Area of farm land bought = 9600m²
Convert m² to km²
1m² = 1e-6 km²
9600m² = 0.000001 * 9600
9600m² = 0.0576km²
Total area on km² = 0.037km²+0.0576km²
Total area on km² = 0.0946km²

Explanation:
In any academic writing, citation of the works used is an important factor. And for that, there are several formats or styles accepted as the correct form, among which is the MLA (Modern Language Association).
According to the MLA format, the works cited list must be in a certain format. As with all citations, the author's last name followed by the remaining names will come first. Then the title of the book followed by the book’s name. Then comes the publisher's name, publishing date, and the page number from which the citation is taken.
Thus, the correct answer is option A.

Find angle3 which is 80º
All lines are 180º
which means angle3+ angle4 is 180º
180º - 80º
= 100º
Answer: B. 100°
Step-by-step explanation:
Since triangles contain angles that add up to 180°, angles 3 is 80°. Since Straight Angles are 180°, it means that angle 4 is 180-80, which equals 100°.
350 students signed up what percent signed up for the airforce (64)
Answer: 18.29%
Step-by-step explanation:
There are 350 students. Out of these students, 70 signed up for the Army, 64 for the Airforce, 56 for the Navy and 160 for the Marines for a total of 350.
The percentage of students who signed up for the Airforce out of the total can be calculated by:
= number of students (airforce) / total number of students * 100
= 64/350 * 100
= 18.29%
Find the solution of the system of equations 3x+3y=6
9x-5y=-24
Answer:
Then the answer to the system is the point (-1, 3)
which corresponds to x = -1 and y = 3
Step-by-step explanation:
Start by dividing the first equation by 3 on both sides, and get:
x + y = 2
now multiply it by 5 in order to be able to eliminate the term in y in the combining of both equations:
5 x + 5 y = 10
+
9 x - 5 y = - 24
___________
14 x + 0 = -14
solve for x by dividing both sides by 14:
x = -14/14 = -1
Use the x = -1 answer in the equation 3 x + 3 y = 6 and solve for y:
-3 + 3 y = 6
add 3 on both sides:
3 y = 9
divide both sides by 3 to isolate y:
y = 3
Then the answer to the system is the point on the plane (-1, 3)
which corresponds to x = -1 and y = 3
A scale of 1:20 is used to make the drawing of a car if the length of the drawing is 10 what is the real length of the car?
Answer: 200
Step-by-step explanation:
since 10 is one part
10 x 20 = 200
The real length of the car will be 200 units.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A scale of 1:20 is used to make the drawing of a car.
And, The length of the drawing is 10.
Now,
Since, The length of the drawing is 10.
And, The used scale = 1 : 20
Hence, The real length of the car = 20 × 10
= 200 units

(6x+8)
Answer:
x = 10
Step-by-step explanation:
This is a parallel line cut by a transversal.
The two angles are corresponding angles. Therefore, they are equal to each other.
6x+8 = 68 >> subtract 8 from both sides
6x = 60 >> divide both sides by 6 to get x alone
x = 10
you can check by substituting 10 as x and see if 6x+8 is equal to 68 which it is
