2 4/5 + 2 3/5 = 4 7/5 = 4+1+2/5 = 5 2/5
Answer:
(x+4)(x+2)
Step-by-step explanation:
Distributive property of 2 binomials:
First, outer, inner, last
(a+b)(c+d) = ac+ad+bc +bd
Factor x^2 into x*x
Factor 8 into 2*2*2
Find what two numbers add up to 6 and multiply to get 8
1 and 8 do not work because they add up to 9. 2 and 4 work because they add up to 6.
Check: (x+4)(x+2)
First: x*x = x^2
Outer: 2*x
Inner: 4*x
Last: 2*4 = 8
Add together: x^2+2x+4x+8 = x^2+6x+8
Answer:
a. 36°

The same figure will reappear when rotated 360°/10 = 36° about the center.
___
<em>Comment on the question</em>
The question as worded is nonsense. If the figure is rotated at all, there is not enough information to tell what the angle of rotation might be.
I think it is b not 100% tho
