Answer:
Step-by-step explanation:
y = 2x^2 - 4x - 5.......if x = -2
so sub in -2 for x
y = 2(-2^2) - 4(-2) - 5
= 2(4) + 8 - 5
= 8 + 8 - 5
= 11 <==== y is 11
Answer is 12.73
Use Pythagorean theory
Split square into two right triangles with diagonal line. To find the diagonal
a^2 + b^2 = c^2
9^2 + 9^2 = c^2
162= c^2
Take square root of both sides
12.73 = c
Answer:
ur right
it's -1013
bc you need to do multiplication first so the equation turns out to be
10 - 1000 - 23
so then that turns to -1013 if you calculate left to right

Answer:
CG = 19
FB = 14.7
Step-by-step explanation:
The circumcenter is equidistant from the triangle vertices, so GA = GB = GC.
The length of GA is given, so we have ...
GA = 19 = CG
__
Then the Pythagorean theorem can be used to find FB.
FB² +FG² = GB²
FB² = GB² -FG² = 19² -12² = 217
FB = √217 ≈ 14.7
