Answer:
B
Step-by-step explanation:
∠ACE and ∠ECB form a straight angle whose sum = 180°, hence
2x + 2 + 5x + 3 = 180
7x + 5 = 180 ( subtract 5 from both sides )
7x = 175 ( divide both sides by 7 )
x = 25 → C
Answer:
3840 cubic inches
Step-by-step explanation:
The volume of a rectangular prism is 960 cubic inches
Let the dimensions be lXwXh,
l=length of the base
w=width of the base
h=height of the base
The volume, lwh=960 cubic inches
If the dimensions of the base are doubled and the height remains the same
Volume of the new rectangular prism=2l X 2w X h =4lwh
=4 X 960 =3840 cubic inches
Answer:
(2x+5) (3x-7)
Step-by-step explanation:
(2x+5) (3x-7) is correct cause you multiply the two sides to get the answer

The club currently have 25 members
Yolanda's club requires that 80% of the members be present for any vote. If at least 20 members must be present to have a vote, it means that 80% of the members in Yolanda's club is 20 members.
In order to determine the number of members in the club, use this formula:
Number of members in the club = least number of members that have to be present to vote / percentage of members that must be present to vote
least number of members that have to be present to vote = 20
percentage of people that must be present to vote = 80%
20 / 0.8 = 25 members
