The number would be -10.8
19 + (-10.8) = 8.2
I hope that helps!
Factorize the left hand side and equate the factors to zero.
Then, use the notation that : sec x = 1/cosx and csc x = 1/sinx
Result: x = ± π3 + 2πk , k∈Z
Answer:
I think its 2 times the original volume, im so sorry if im wrong!!
Step-by-step explanation:
Edit: I thought it was two but i guess it was 4, heres the real answer for people who were wondering, im so sorry!!
Answer:
70
Step-by-step explanation:
In parallelogram ABCD, diagonals AC and BD intersect at point E
E is the midpoint of BD
So BE = DE
Given: BE =2x^2-3x, and DE=x^2+10
BE = DE
(solve for x)
Subtract x^2 and 10 on both sides
Factor x^2-3x-10
(x-5)(x+2) = 0
x-5 =0 so x=5
x+2=0 so x=-2
Length x cannot be negative so we ignore x=-2
Lets plug in 5 for x and find out BE and DE
BE =
DE =
BD = BE + DE= 35+35 = 70
So BD = 70
Distribute the negative first -7c+18-2>0
simplify -7c+16>0
subtract 16 both sides -7c>-16
divide by -1
MOST IMPORTANT PART
when you divide both sides by -1, you HAVE to change the greater/less than sign
so -7c>-16 becomes 7c<16
now divide by 7
c<16/7
I hope you don't yet want to graph it, because graphing is something that's a bit harder to show here
