Answer:
His interest is $2340 his total is $8840
Step-by-step explanation:
(4x - 2) x (12x +42) (I distributed the 6 over the 2x and the 7)
Using the FOIL method
First terms (in each parenthesis) 4x times 12 x = 48x²
Outer terms 4x times 42 = 168x
Inner terms -2 times 12 x = -24x
Last terms -2 times 42 = -84
So we have 48x² + 168x + 168x - 24x -84
Finally combine like terms:
48x² + 144x - 84 There's your quadratic expression
Answer:
Option (2)
Step-by-step explanation:
From the table attached.
First column is representing the x-values (input values) and second column is representing the value of the function (output values).
For x = -6,
f(x) = 8
For x = 7,
f(x) = 3
For x = 4,
f(x) = -5
For x = 3,
f(x) = -2
For x = -5,
f(x) = 12
Therefore, f(x) = -2 is one of the output values.
Option (2) will be the correct option.
Answer:
Corroponding side lengths are equal
Step-by-step explanation:
Two triangles may have the same areas, but the sides might be different or in different spots than each other. The same goes for perimeter, therefore it doesn't mean that they are congruent. If two triangles had the same angle measures, it could still have any size side lengths. When corrosponding side lengths are equal, they have the same angles as well, so they are only congruent in this example.
Hope this helps :)
The answer is 50,51 and 52
