Answer:
[tex]12a^{7}b^{9}[/tex]
Step-by-step explanation:
The laws of exponents state that when multiplying exponents of the same base, you can add the exponents. Therefore, [tex]a^{3}*a^{6}=a^{3+6}[/tex], or [tex]a^{9}[/tex]. Same with the b's. [tex]b^{2}*b^{5}=b^{7}[/tex]. Multiplying 4*3 is easy; 12. Multiply all together and you get [tex]12a^{9}b^{7}[/tex].

The length of a living room is 12 feet and its width is 10.5 feet. The length of the room is being expanded by x feet.
A. Write an expression to represent the new area of the living room in square feet.
B. Expand the expression.
Answer:
A) A= 10.5(12 +x)
B) A= 10.5x +126
Step-by-step explanation:
A) Length of living room= 12 ft
Width= 10.5 ft
Since the length expanded by x ft,
New length of living room= (12 +x) ft
Area= length ×width
Let the new area of the living room be A ft².
A= 10.5(12+x)
B) To expand the expression, multiply 10 to each term and constant in the bracket on the right hand side of the equation.
A= 10.5(12 +x)
A= 10.5(12) +10.5x
A= 126 +10.5x
please explain how to do this system of equations 2y=6x+10 y=2x+4
Answer:
x=-1, y=2
Step-by-step explanation:
Given:
2y=6x+10
y=2x+4
Substitution for y into first equation:
2(2x+4)=6x+10
4x+8=6x+10
0=2x+2
2x=-2
x=-1
y=2(-1)+4
y=2
The cost in dollars of making x items is given by the function C(x)=10x+800.
a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item.
b. What is the cost of making 25 items?
c. Suppose the maximum cost allowed is $3300. What are the domain and range of the cost function, C(x)? (In interval Notation)
C(x) = 10x+500
A. C(O)=A 10.0+500. = 500.e
B. C(25) = 10.25+500 =750
C.c(x)=1500=10x+500

Translate and solve: 662% of what number is 3641?
Answer:
550Step-by-step explanation:
To find the percent of a number, we multiply the number by the decimal form of the percent. The decimal form of a percent can be found by moving the decimal point two places to the left.
Example: 45% = 0.45
In this case, we need to work backward. So, instead of multiplying, we will divide to undo the multiplication.
662% = 6.62
We need to divide 3641 by 6.62 to get the number that 3641 is 662% of. This number will be a smaller number since 662% of a number will be larger than the original number, This is because it is greater than 100%, which would be the number.
Example 100% of 6 is 6 since 6 x 1.00 is 6.
3641/6.62 = 550
However, we can also verify this by multiplying 550 by 6.62 to find 662% of 550.
6.62 x 550 = 3641
