Ax^2+bx+c
if a=1, then
take 1/2 of b and square it
w^2-4w+c
b=-4
-4/2=-2, (-2)^2=4
add that
w^2-4w+4
(w-2)(w-2)
(w-2)^2
to make it into perfect squres, add 4
It is different because to find out the answer, change all denominators to 10, since the LCD is 10.
6/10-5/10=1/10
6/10-6/10=0/10
1/10 is not equal to 0/10
Answer:
largest angle measures 108°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
8x - 6 + 108 + 14 = 180, simplify left side
8x + 116 = 180 ( subtract 116 from both sides )
8x = 64 ( divide both sides by 8 )
x = 8
Thus
∠ U = 8x - 6 = 8(8) - 6 = 64 - 6 = 58°
Then the largest angle measures 108° ( ∠ B )
Answer:
f = 78 , g = 32 , h = 74
Step-by-step explanation:
f and 78° are alternate angles and are congruent , then
f = 78
---------------------------
h and 74° are alternate angles and are congruent , so
h = 74
--------------------------
the sum of the 3 angles in the triangle = 180°
sum the 3 angles and equate to 180
78 + g + h = 180
78 + g + 74 = 180
152 + g = 180 ( subtract 152 from both sides )
g = 28
<span>If the part needs to be 5.72 inches long, with a tolerance of 0,02 inches (I cannot read the symbol before 0.02, so will assume it's meant to be +/-), the part length must be in the range 5.70 to 5.74. If the part is now 5.85 inches, the most it can be shortened by is 0.15 inches.</span>
