Answer:
f(x) +g(x) = 4x^2 +3
f(x) -g(x) = 4x^2 -6x +1
f(x)·g(x) = 12x^3 -5x^2 +3x +2
Step-by-step explanation:
Substitute for f(x) and g(x) and simplify.
(a) f(x) +g(x) = (4x^2 -3x +2) +(3x +1)
f(x) +g(x) = 4x^2 +3
__
(b) f(x) -g(x) = (4x^2 -3x +2) -(3x +1)
f(x) -g(x) = 4x^2 -6x +1
__
(c) f(x)·g(x) = (4x^2 -3x +2)(3x +1)
= (4x^2 -3x +2)(3x) +(4x^2 -3x +2)(1) . . . use the distributive property
= 12x^3 -9x^2 +6x +4x^2 -3x +2
f(x)·g(x) = 12x^3 -5x^2 +3x +2
Answer:
a.) f( x ) + g( x ) = 4 x² + 3
b.) f( x ) - g ( x ) = 4x² -6x + 3
c.)f ( x ) . g ( x ) = 12x³ - 5x² + 3x + 2
Step-by-step explanation:
Given :- f ( x) = 4x² - 3x + 2 and g(x)= 3x +1
Substitute the values of f(x) and g(x) and simplify all .
a.) f( x ) + g( x )
( 4x² - 3x + 2 ) + ( 3x + 1 )
4 x² - 3x + 2 + 3 x + 1
collect like terms
4x² - 3 x + 3 x + 2 + 1
4 x² + 3
b.) f ( x ) - g ( x )
( 4x² - 3x + 2 ) - ( 3x + 1 )
4x² - 3x + 2 - 3x - 1
collect like terms
4x² - 3 x - 3x + 2 - 1
4x² -6x + 1
c.) f ( x ) . g ( x )
( 4x² - 3x + 2 ) × ( 3x + 1 )
Use the Distributive property
3 x(4x² - 3x + 2 ) × 1 ( 4x² - 3x + 2 )
Remove the parantheses multiply
12x³ - 9x² + 6x + 4x² - 3x + 2
Collect like terms
12 x³- 9x ² + 4x² + 6x - 3x + 2
12x³ - 5x² + 3x + 2

John writes a number sequence starting with 8. Write the next number 8, 22, 36, _______
Answers
Answer:
50
Step-by-step explanation:
from the question that we have been given, we have to find out the next number after 36.
John's next number sequence will be 50. Every number after 8 can be gotten by adding 14. So when we add 14 to 36, we get the final answer, which is the next number in the sequence.
This can be seen below:
14 + 8 = 22
14 +22 =36
14 +36 =50
therefore the next sequence would be 50

Write the equation of the line parallel to y=2x+7 and contains the points (6,-1)
Answers
Answer: y = 2x - 13
Step-by-step explanation: Start with the formula y=mx+b. Remember that the slope of the parallel line, m, is the same. Now you have y = 2x + b. You can find b, the y intercept, knowing that the line passes through the point given: -1 = (2) * 6 + b. So now we see that b = -13.

Jim took out a loan for $500 . The rate is 8%. How much does Jim owe in interest if he plays it back in 4 1/2 years?
What is the balance that jim owes for his loan?
Answers
Answer:
If jim pays the loan back in 4 1/2 years he will be paying $597.03
Step-by-step explanation:
As per simple interest, Jim owes $180 in interest.
Jim owes a balance of $680 for his loan.
What is a simple interest?"By definition, simple interest is the interest amount for a particular principal amount of money at some rate of interest."
Given, the loan amount is P = $500.
The rate of interest is i = 8% = 0.08.
The duration is [tex]4\frac{1}{2}[/tex] years t = 4.5 years.
Therefore, the interest after the mentioned period
= (P × i × t)
= $(500 × 0.08 × 4.5)
= $180
Therefore, Jim owes $180 in interest if he pays it back in mentioned time period.
The balance that Jim owes for loan is
= $(500 + 180)
= $680

on the map represents 3 ft. If the first hallway has a length of 120 ft, what
should the length of the hallway be on the map?
O
a. 40 cm
b. 60 cm
C. 30 cm
d. 45 cm
Answers
Answer:
The answer is 60cm. (b)
Step-by-step explanation:
For every 1.5cm on the map, it represents 3 ft on real-size scale.
In other words, for every 1cm on the map, it represents 3/1.5 = 2ft on real size scale.
If you want to find 120ft of real-size scale, you can use 120ft/2ft * 1cm which gives 60cm

Answer:
148cm²
Step-by-step explanation:
With the first frontal face of the cuboid, you have length 6 cm whilst the height remains 5 cm.
Find the area of this face and multiply the result by 2, as there are two of these faces (front and back)
6 x 5 = 30 cm²
30 x 2 = 60cm²
Do the same with the top face and bottom face, adding this with the side faces
4 x 6 = 24cm²
24 x 2 = 48cm²
4 x 5 = 20cm² x 2 = 40 cm²
40 + 48 + 60 = 148 cm²
T.S.A = 148cm²
