3n=27+3
you can do anything as long as you do it to both sides
3n=27+3
add like terms
27+3=30
3n=30
divide both sides by 3
n=10
(1)
f(x) + g(x) = 3x + 2 + 2x + 5 = 5x + 7
f(x) - g(x) = 3x + 2 - 2x - 5 = x - 3
(2)
f(x) + g(x) = 4x - 1 + 3x - 4 = 7x - 5
f(x) - g(x) = 4x - 1 - 3x + 4 = x + 3
(3)
f(x) + g(x) = - 5x + 3 + 2x - 4 = - 3x - 1
f(x) - g(x) = - 5x + 3 - 2x + 4 = - 7x + 7
(4)
f(x) + g(x) = 3x - 4 - 2x + 3 = x - 1
f(x) - g(x) = 3x - 4 + 2x - 3 = 5x - 7
(5)
f(x) × g(x) = - 2(- x + 7 ) = 2x - 14
(6)
f(x) × g(x) = - 5(2x - 7) = - 10x + 35
Answer:
20 square units
Step-by-step explanation:
we know that
The area of rectangle is equal to
In this problem
the formula to calculate the distance between two points is equal to
<em>Find the distance WX</em>
we have
W(-3,1), X(3,3)
substitute the values in the formula
<em>Find the distance XY</em>
we have
X(3,3),Y(4,0)
substitute the values in the formula
<em>Find the area of rectangle</em>
substitute the values

To solve this plug in 9 for b and solve for a like so...
3a + 9 = 54
9 must be combined with 54. To do this you must subtract 9 from both sides. This will cancel out 9 from the left and bring it over to the right
3a + (9 - 9) = 54 - 9
3a + 0 = 45
3a = 45
Now we must isolate the a. To do this you have to divide 3 to both sides. This will make 3 on the left side 1 and bring 3 over to the other side
3a/3 = 45/3
1a = 15
a = 15
Hope this helped!
