Answer:
x>-2
Step-by-step explanation:
Simplify both sides of the inequality.
4x+3>−5
Subtract 3 from both sides.
4x+3−3>−5−3
4x>−8
Divide both sides by 4.
4x/4>-8/4
Answer:
option c
Step-by-step explanation:
(4 - 2i) + (12 + 7i)
multiply the brackets first
4 - 2i + 12 + 7i
combine like terms
16 + 5i
Answer:
655
Step-by-step explanation:
this feels like elementary school maths
<edf is 86 vertical angles
< e + <edf + <efd =180 sum of the angles of a triangle
42+ +86 +<efd =180
128 + <efd = 180
subtract 128 from each side
<efd = 52
<efd + <dfg = 180 straight line
52+ <dfg = 180
subtract 52 from each side
<dfg = 128
Answer : 128
To factor a cube (a^3-b^3) = (a-b)(a^2+ab+b^2)
8 is the cube of 2
r^3 is the cube of r.
So, a is 2 and b is r
(2-r)(2^2+2r+r^2)
(2-r)(4+2r+r^2)
