Answer:
<A = 44
Step-by-step explanation:
A triangle is 180 degrees
(x+59) + (x+51) + 84 = 180 >> add everything on the left side
2x + 194 = 180 >> subtract both sides by 194
2x = -14 >> divide both sides by 2 to get x alone
x = -7
since you are finding A<, substitute
<A = x + 51
<A = (-7) + 51
<A = 44
Answer:
im pretty sure it's d
Step-by-step explanation:
because i put that and i got a good grade
Answer:
-5x=y-5-2y=-x-21
y-5-2y=-21/4-21
y=85/4
(x,y)=(21/4,85/4)
Okay so first off I do not know if any of these are completely correct, as well as I totally forgot how to solve the last two. Either way, this is what I got for them.
The first is true
The second would be true although -88 squared is 7744 and the equation equals -7744 which can not be obtained by a square number of negative times a negative is a positive number. The third is not true for you do have -a^2 and -b^2 but you also end up with aB as well as -bA. The fourth in decimal form would be.167 The fifth again in decimal form would be 1.732 Then the next would be 0. Finally, the next one would be .090 Again, I do not know how to solve the last two and I honestly do not know if anyone of these is correct.
Answer:
=2g+9
Step-by-step explanation:
5g+14−3g−5
=5g+14+−3g+−5
=5g+14+−3g+−5
=(5g+−3g)+(14+−5)
=2g+9
