Hello!
A)
The area of a rectangle is L * W.
- Area = (6x + 4)(2x + 11)
- Area = 12x² + 8x + 66x + 44
- Area = 12x² + 74x + 44
B)
The degree of a polynomial is the value of the highest exponent. The degree of 12x² + 74x + 44 is 2, because 2 is the highest exponent.
C)
This demonstrates the closure property, as adding, subtracting, and or multiplying polynomials will give a polynomial.
Answer:
$13.94
Step-by-step explanation:
$14.93 + $11.13= 26.06
$20+$20= $40.00
$40.00 - 26.06 = $13.94
Hope this helps!
Start with your given equation - F=9/5C+32
Subtract 32 from both sides - F-32=(9/5) degrees C
Multiply both sides by 5 - 5(F-32)=9C
Divide both sides by 9 to isolate C - (5/9)(F-32)=C
Answer - C=(5/9)(F-32)

Answer:
First, you have to form simultaneous equation for both of their ages in yerms of a and b :
b = 4a - 12 -------- ( 1 )
a + b = 28 -------- ( 2 )
Next, you will have to solve it by substituting ( 1 ) into ( 2 ) :
a + (4a - 12) = 28
5a - 12 = 28
5a = 28 + 12
5a = 40
a = 8
Then, substitute a = 8 into ( 1 ) :
b = 4(8) - 12
b = 32 - 12
b = 20
Answer:
Complement: 118°. Supplement: 28°
Step-by-step explanation:
To determine the supplement, subtract the given angle from 180.
180 - 62 = 118
To determine the complement, subtract the given angle from 90.
90 - 62 = 28
