2
Step-by-step explanation:
In this case, you have to substitute the w for -1, and then do the operation:
-6( -1 )^2 + 13( -1 ) + 21
-6( 1 ) - 13 +21
-6 -13 + 21
-19 + 21

K+ 3k = 940
4k= 940
K= 940/4
K= 235
H= 3k
H= 3×>235 = 705
K= 235
H= 705

solve the equation for X by finding a,b, and c of the quadratic then applying the quadratic formula.
Answer:
Step-by-step explanation:
The protractor has inner and outer readings. The inner reading has graduations with intervals of 10 degrees and the outer reading also has graduations with intervals of 10 degree. We will use the outer graduations to take readings. On the outer reading, the shortest graduations is in intervals of 1 degree while the shorter graduation is in intervals of 5 degrees. Therefore,
a) angle AFB is 55 degrees
b) angle BFE is 180 - 55 = 125 degrees.
c) angle DFA is 126 degrees
d) angle BFD is 60 + 5 + 6 = 71 degrees.
e) angle CFD is 36 degrees
The answer is 46. Hope this helps!
