Answer:
(x + 5)²
Step-by-step explanation:
To get this we must find a binomial that multiplies by itself to get x² + 10x + 25.
(x + 5)(x + 5)
= x² + 5x + 5x + 25
= x² + 10x + 25
Answer:
6.75
Step-by-step explanation:
2+10+1+8+12+6+23+5+8+4+4+3+2.59+5.11+5.18+9.07 = 107.95
now we count how much numbers you added up which equals 16 and divide it with 107.95
107.95/16 = 6.746875
now you cant pay half a penny or such and such
so your round it off at 6.746 to 6.75
and there you have it
Answer:
x=2, x=-5
Step-by-step explanation:
to work more comfortably, the first thing we need to do is work the equation linearly, for that we take advantage of the property of logarithms that tells me that 
in this way, the equation remains as:

Now we clear the equation so that it is of the form 

finally, we apply the equation to solve second degree equations


x=2 and x=-5
Done
This is a kite due to the adjacent congruent sides (shown by the tickmarks). With any kite, the diagonals are perpendicular. So angle 3 is 90 degrees.
