The answer is 2(5x - 4)(x + 1)
10x² + 2x - 8 = 2*5x² + 2*x - 2*4 =
= 2(5x² + x - 4) =
= 2(5x² + 5x - 4x - 4) =
= 2(5x *x + 5x*1) - (4*x + 4*1) =
= 2(5x(x + 1) - 4(x + 1)) =
= 2(5x - 4)(x + 1)
It will graph a straight horizontal line at -1
You get the expression;
3H-21
Hope this helps.
Apply the Law of Sines.
sinB/b = sinA/a
sinB/3 = sin(30°)/2
sinB = (3/2)sin(30°) = 0.75
Therefore
bsinA = 3*sin(30) = 1.5
0.5b = 0.5*3 = 1.5
Answer:
There is exactly one triangle because b sinA = 0.5b.
Answer:
Number 2 is A
Step-by-step explanation:
5 is 380% because 405-22 is 383 if you round that it is 380%
