Answer:
True
If the angles are equal A and B are parallel
Option 1 : -22
using formula
(a + b )(a - b ) = a^2 - b^2
(√10 + 2√8) (√10 - 2√8)
= (√10)^2 - (2√8)^2
= 10 - 2×2×8=10-32
= -22
2nd question answer is option 3
Answer: It already tells you what DE= 60
Step-by-step explanation:
Since F is the midpoint of DE that means DF=FE
So create equation 
When DF and FE is added your answer should equal DE
So you write the equation
to find x and once x is found substitute your answer for x
subtract 12 on both sides 36-12= 24
subtract 2x on both sides 4x-2x=2x
divide 2 into both sides 24/2=12 x=12
4x12=48+12=60 2x12=24+36=60
It would be the second one... y=3x^2+10
Answer:

Step-by-step explanation:
From the Empirical Rule, 95% of the data shown falls between 63 and 95. The other 5% is evenly distributed to each side (since the distribution is bell-shaped), hence there being
of scores less than 63.
The directions say to give the approximate percentage which is vague. You may have to input
if it does not accept
