Answer:
27
Step-by-step explanation:
45+27=72 and the overall angle is 72
4 + (14 - 2) = 4 + 14 - 2
A. 4 - (-14 - 2) = 4 + 14 + 2 ------------------------WRONG
B. (4 - 14 ) - 2 = 4 - 14 - 2 --------------------------WRONG
C. 4 - (-14) - (2) = 4 + 14 - 2 ------------------------RIGHT
D. 4 + 14 + (-2) = 4 + 14 - 2 ------------------------RIGHT
E. - (-4 - 14) - 2 = 4 + 14 - 2 ------------------------RIGHT
Answer: C, D and E.
Remember, you take 1/2 of b and square it to get c
c=100
(b/2)^2=c
(b/2)^2=100
sqrt oth sides
b/2=+/-10
times both sides by 2
b=+/-20
it is 20 or -20
answe ris B
yo is right
Answer:
There are none.
Step-by-step explanation:
<u>No calculus involved:</u>
The line, in slope-intercept form, has equation 
, ie is always decreasing (easy to spot applying the definition)
Meanwhile, 
is always increasing over its domain.
At no point the tangent will be decreasing.
<u>Let's use calculus</u>
We are to solve the equation 
which has no real solutions.
