Answer:
I am not entirely sure what you are asking, but I believe the answer is 4*2=8
Step-by-step explanation:
This is because:
8 increased by the product of a number and 4 is at most 20.
8 + <em>p</em> + 4 = 20
We are trying to find <em>p</em>.
8 +4= 12
20 - 12= 8
So I believe the answer is 8.

Uncorrectly:5 => -5
unanswered:2 =>0 points
20x4=80 points in total(only correct awnsers)
=>20-5+2=13 correct awnsers
13x4=52
52-5=47
It will be nice if you give me brainliest. Good luck!
Answer:
Step-by-step explanation:
2x^2 + 6x - 4 = 0
AE = AC = 4
m<CAB = 60 (equilateral triangle)
m<CAE = 90 (square)
m<BAE = 150 (= 60 + 90)
Triangle BAE is isosceles since AB = AE;
therefore, m<AEB = m<ABE.
m<AEB + m<ABE + m<BAE = 180
m<AEB + m< ABE + 150 = 180
m<AEB + m<AEB = 30
m<AEB = 15
In triangle ABE, we know AE = AB = 4;
we also know m<BAE = 150, and m<AEB = 15.
We can use the law of sines to find BE.
BE/(sin 150) = 4/(sin 15)
BE = (4 sin 150)/(sin 15)
BE = 7.727
