Answer:
x + x + x + x is the same as 4x
because its "x four times"
5x and x+5 are not the same because x+5 in not "x five times"
5x is 5 multiplied by x.
x + 5 is 5 added to x.

Answer:
x = 16
Step-by-step explanation:
Either or both of the right triangles can be used to find x. Or, triangle ABC could be used. All numbers are assumed to be degrees.
<u>Using ∆ABD</u>
55 +90 +2x+3 = 180
2x = 32 . . . . . . subtract 148
x = 16
<u>Using ∆BCD</u>
50 +90 +2x+8 = 180
2x = 32 . . . . . . subtract 148
x = 16
<u>Using ∆ABC</u>
55 +(2x +3) +50 +(2x +8) = 180
4x = 64 . . . . . . . subtract 116
x = 16
The correct answer is: [B]: " 3 " .

If (5⁴)ᵐ = 5¹² ; then what is "m" ?
Note the following property of exponents:
________________________________________________
(xᵃ)ᵇ = x⁽ᵃ*ᵇ⁾ ; a≠0 ; b ≠ 0 ;
Then, (5⁴)³ = 5⁽⁴ * ³⁾ = 5¹² .
So, "12 ÷ 4 = 3" .

Answer:
3/6, 2/6.
Step-by-step explanation:
The lowest common denominator of 2 and 3 is 6.
1/2 = 3/6 and 1/3 = 2/6
So this pair of fractions is 3/6, 2/6.
