Answer:
b = -
Step-by-step explanation:
Given
5(b + 6) = 18 ← distribute left side
5b + 30 = 18 ( subtract 30 from both sides )
5b = - 12 ( divide both sides by 5 )
b = - = - 2.4
Answer:
yes he is correct. he spent 125% more time
Step-by-step explanation:
his original time spent was 20 hours
he spent a new time which is 25 hours
increased time = 25- 20 = 5 hours
% increase = increase/ original ×100%
%increase = 5/ 20 ×100%
= 1/4 ×100%
= 25%
total increment = 100 + 25 =125%

Step-by-step explanation:
Hi!
You know that if f(p) = 0, then (x-p) is a factor of the polynomial f(x)
Then, f(3)=0 is the case p=0, son the factor is (x-3)
Answer: Since we are told that f(3) = 0, we know that (x-3) is a factor.
Answer: 9.95
Step-by-step explanation:
in similar trapezoids a rearranged formula can be used to solve for the missing base:
⇒
a = the top of the trapezoid
b= the base of the trapezoid
c = the missing base
