Answer:

Step-by-step explanation:

Squaring both sides of the equation would give
which then simplifies to 
We can then subtract 7 from both sides to get 
Then we can subtract x from both sides, which cancel out and we get 
Then we need to divide both sides by -2 to get 
Then we need to square both sides
to get rid of the square root to get 9 = x + 6
Then finally subtracting 6 from both sides we get 3 = x

Answer:
The members of the cabinet can be appointed in 121,080,960 different ways.
Step-by-step explanation:
The rank is important(matters), which means that the order in which the candidates are chosen is important. That is, if we exchange the position of two candidates, it is a new outcome. So we use the permutations formula to solve this quesiton.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:

If there are 14 eligible candidates for these positions (where rank matters), how many different ways can the members of the cabinet be appointed?
Permutations of 8 from a set of 14. So

The members of the cabinet can be appointed in 121,080,960 different ways.
Answer: <B is congruent to <E
Step-by-step explanation:
There is no “angle,angle,angle” theorem when proving triangles are congruent.
There are 5 however that do:
ASA (angle, included side, angle)
SSS (side, side, side)
SAS (side, included angle, side)
AAS (angle,angle, non included side)
HL (hypotenuse,leg)
It is positive.
Hope this helped.
