Answer:
yes, correct
Step-by-step explanation:
6c - 48 = 6*c - 6 *8
= 6* (c-8)
Answer:
Since 
, the superhero makes it over the building.
Step-by-step explanation:
The height is given by the following function:
Will the superhero make it over the building?
We have to find if there is values of x for which f(x) = 612.
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots 
such that 
, given by the following formulas:
If 
, the polynomial has no solutions.
In this question:
We have to find 
We have that 
. So
Since , the superhero makes it over the building.
Answer:
5(2x(2x + 3) - 3 ( 2x +) or 5(2x -3) (2x + 3)
Answer:
The correct answer is - 625.36.
Step-by-step explanation:
Given:
Fixed mothly plan - 616
free minutes - 150
Used minutes - 170
Free text - 150
Used text - 182
Charging amount over free limit - 18p
Solution:
Number of minutes over the limit - 170 - 150 = 20
Number of text over the limit - 182 - 150 = 32
So the extra amount that will be add to the monthly charge would be -
(20*0.18) +(32*0.18)
and the total charge of the month would be -
= 616+(20*0.18) +(32*0.18)
= 616+3.60+5.76
= 625.36
Thus, the correct answer would be - 625.36
