Answer:
The last one
Step-by-step explanation:
This is because 8x2 is doubling8 and then it also asks to multiply 4 and 2
Lastly it says subtract second number from first which means subtract 4 by 2 from 8 by 2
Hope this makes sense
Simplify the expression:
a (-8a^2 + 2a + 4) +3 (ba^2 - 4)
Answer:
4 a + 2 a^2 - 8 a^3 + 3 a^2 b - 12
Step-by-step explanation:
Simplify the following:
3 (b a^2 - 4) + a (-8 a^2 + 2 a + 4)
Hint: | Distribute a over -8 a^2 + 2 a + 4.
a (-8 a^2 + 2 a + 4) = -8 a^3 + 2 a^2 + 4 a:
-8 a^3 + 2 a^2 + 4 a + 3 (b a^2 - 4)
Hint: | Distribute 3 over a^2 b - 4.
3 (a^2 b - 4) = 3 a^2 b - 12:
Answer: 4 a + 2 a^2 - 8 a^3 + 3 a^2 b - 12

In the figure below, m∠1 = x and m∠2 = x - 8. Which statement could be used to prove that x = 49?
Answer:
see explanation
Step-by-step explanation:
∠ 1 + ∠ 2 = 90, that is
x + x - 8 = 90
2x - 8 = 90 ( add 8 to both sides )
2x = 98 ( divide both sides by 2 )
x = 49
A group of friends were working on a student film that had a budget of $1200. They spent all their budget on costumes and equipment. They used 33% of their budget on equipment. How much money did they spend on costumes?
Answer:
$804
Step-by-step explanation:
33%=0.33----Covert the percentage as a decimal.
0.33*1200=396----Multiply the decimal by the price of budget. This is the cost of equipment.
$1200-$396=$804----Subtract the cost of equipment ($396) by the cost of budget($1200). You get $804!
Hope this helped.

Answer:
JM = 20
Step-by-step explanation:
Find the value of JM
Using similar triangles;
MJ/HN = GJ/HK
GJ+JM/HN = GJ/HK
15+JM/12+16 = 15/12
15+JM/28 = 15/12
Cross multiply
12(15+JM) = 15*28
180+12JM = 420
12JM = 420 - 180
12JM = 240
JM = 240/12
JM = 20
Hence the length of JM is 20

Which of the following reveals the minimum value for the equation 2x2 + 12x − 14 = 0? 2(x + 6)2 = 26 2(x + 6)2 = 20 2(x + 3)2 = 32
Answer:
The equation which reveals the minimum value for the equation is 2·x² + 12·x - 14 = 0 is the option;
2·(x + 3)² = 32
Step-by-step explanation:
The given function can be presented as follows;
2·x² + 12·x - 14 = 0
The quadratic equation in standard form is a·(x - h)² + k
Where;
(h, k) is the vertex of the parabola
Given that the coefficient of the x² is positive, the graph is U-shaped and the lowest point is given by the vertex of the graph as follows;
2·x² + 12·x - 14 = 2·x² + 12·x - 14 = 2·(x² + 6·x - 7) = 0
2·(x² + 6·x - 7) = 2·(x² + 6·x + 9 - 7 - 9) = 2·((x + 3)² - 16)
2·((x + 3)² - 16) = 2·(x + 3)² - 32 = 0
∴ 2·x² + 12·x - 14 = 2·(x + 3)² - 32 in vertex form
The minimum value (vertex, (h, k)) for the equation = (-3, -32)
Therefore, the equation which reveals the minimum value for the equation is 2·(x + 3)² = 32
Answer:
2(x + 3)2 = 32

Answer:
204 ft^2
Step-by-step explanation:
triangle on the left:

A = 12 x 5 x 1/2
A = 30 ft^2
triangle on the right:
Same thing
A = 30 ft^2
square in the middle:
A = l x w
A = 12 x 12
A = 144 ft^2
Add them up:
30 + 30 + 144 = 204 ft^2

1. Christina drew a scale model of an Olympic-size swimming pool using a
scale in which 3 centimeters represents 10 meters. If the length of the
pool in her drawing is 15 centimeters, what is the length of the actual
pool?
4,5 m
D 150 m
Answer: 4,5
Step-by-step explanation:
The actual length of the Olympic-size swimming pool which is drawn by Christina on the scale model is 50 meters.
What is scale factor?
Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
Christina drew a scale model of an Olympic-size swimming pool using a scale in which 3 centimeters represents 10 meters.
Thus, the scale factor is for cm to m,
[tex]r=\dfrac{3}{10}\rm[/tex]
The length of the pool in her drawing is 15 centimeters. Let the length of the actual pool is x cm. Thus,
[tex]\dfrac{15}{x}=\dfrac{3}{10}\\x=50\rm \; m[/tex]
Thus, the actual length of the Olympic-size swimming pool which is drawn by Christina on the scale model is 50 meters.

There were 874 tickets sold for a school event. Student tickets were $3 and non-student
tickets were $7. If the total amount of ticket sales was $3,786, how many student
tickets were sold? (Use only the digits 0-9 to enter a number.)
This questions weird
Answer:
583 student tickets
Step-by-step explanation:
This question is likely asking us to set up a system of equations. Let us say that:
x represents the number of student tickets
y represents the number of non-student tickets
We know that there were a total of 874 tickets sold, so:
x + y = 874
We also know that every student ticket was sold for $3 and every non-student ticket was sold for $7. We also know the total sales, so:
3x + 7y = 3786
These are our two equations. We can use substitution to solve for the number of student tickets, x:
x + y = 874
y = 874 - x
3x + 7y = 3786
3x + 7(874 - x) = 3786
3x + 6118 - 7x = 3786
-4x = -2332
x = 583 student tickets
Solve these equations.
