Answer:
B
Step-by-step explanation:
65 is the product of this
x=4x+3
Simplifying
x = 4x + 3
Reorder the terms:
x = 3 + 4x
Solving
x = 3 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
x + -4x = 3 + 4x + -4x
Combine like terms: x + -4x = -3x
-3x = 3 + 4x + -4x
Combine like terms: 4x + -4x = 0
-3x = 3 + 0
-3x = 3
Divide each side by '-3'.
x = -1
Simplifying
x = -1
Answer:
Step-by-step explanation:
given
To rationalise the denominator multiply the numerator/ denominator by the conjugate of the denominator.
the conjugate of 3 - is 3 + , hence
×
= (15 + 5 - 6 - 14 ) / (9 - 7)
= ← in simplified radical form
Angle IAK is 28 degrees.
the line I intersects to parallel running lines. I is 180 degrees. there is an angle given to you which is 62. that angle is also the angle for the where line DE intersect with line IJ. so if line IJ is total 180. minus the 62 angle. is 118. line DE and line KL intersect at a 90 angle. so 118 minus 90 is 28. therefore 28 is the answer to the angle IAK.
i hope this all made sense and helped you (:
