Answer:
10
Step-by-step explanation:
we know that y=sqrt(7), so just plug it into the expression y^2 +3. now we have (sqrt(7))^2 +3, (sqrt(x))^2=x, so (sqrt(7))^2 +3= 7+3=10

Answer:
Step-by-step explanation:
Given the rhombus CDEF, sides FC and CD are adjacent sides.
Using coordinate geometry, to proof that a quadrilateral is a square, with regards to the slope, the slope of adjacent segments must be negative reciprocals.
In fact, by definition: Two lines with slopes 
are perpendicular if:
Therefore if :
- FC and CD are adjacent segments
- Slope of FC=25
For the rhombus to be a square:
Slope of CD 
Answer:
1. 2.474
2. 2.694
3. 2.334
4. 2.638
Step-by-step explanation:
1 = .20 x 12.37 = 2.474
2 = .20 x 13.47 = 2.694
3 = .20 x 11.67 = 2.334
4 = .20 x 13.19 = 2.638
The answer is C=10
This is the Pythagorean theorem, it solves for the hypontunuse. Basically it tells you the missing sides length.
It’s really simple once you get the hang of it. The formula is
A^2+b^2=c^2
Plug in the side lengths you have (6 and 8)
6^2+8^2=c^2
36+64=c^2
100=c^2
DO NOT PUT 100 AS ANSWER
You then take the square root of 100, to get 10^2
