Answer:
perimeter: 4x+2 area: x^2+x
Step-by-step explanation:
for perimeter, you add x+x+x+x+1+1, which is 4x+2
for area, you multiply x*x+1, which would be x^2+x
Answer:
it is on the nearest tenth. The number on the other side of the dot are tenths
Question 1. is C
question 2. is <span>There is not enough information to prove that the triangles are congruent. The </span>ongruence statement can you write about the triangles in the previous problem is <span>△JFE≅△SFV
question 3. i think itd be D</span>
Christy dove to the depth of 12 feet below the surface = -12 feet
(Below sea level means to be below zero, which are negative numbers)
Christy dove 12 feet back up to the surface= +12 feet
( When we come back up to the surface, the distance is taken always positive)
Therefore, we have to find the overall change,
Overall change = -12 feet + 12 feet
= -12 feet + 12 feet
= 0 ft.
Therefore, overall change is 0 ft.
