19.00 3.50 11.00 4.47 makes it add up to hours so that will be answe C
Answer:
(2x+1) (x+4)
Explanation:
The idea is to break down the middle term into two monomials which can be used in the factorization process. Note that
2.4=8=8.1
, and that we may write 9=8+1
, which may help us in the process.
Let us write:
2x^2+9x+4
=2x^2+8x+x+4
=2x(x+4)+(+4)
=(2x+1)(x+4)
Answer:
a) yes
b) no
c) no
Step-by-step explanation:
a) The percentage change from 12 to 15 is ...
(15/12 -1)·100% = 1/4·100% = 25% . . . . between 20% and 30%
__
b) The height increased by 61-52 = 9 inches. 20% of 52 inches is 10.4 inches, so the increase was less than 20%.
__
c) The increase was negative, so was not between two positive values.
___
In summary ...
a) yes, 25% is between 20% and 30%
b) no, 17.3% is NOT between 20% and 30%
c) no, -33.3% is NOT between 20% and 30%
_____
A percentage change can be calculated from ...
((new value)/(old value) -1) × 100%
