Answer:
the last option of 135°.
Step-by-step explanation:
The total degree of the rectangle is 360°. But it was sliced, so with the remaining measurements, subtract each of them from 360°.
90°+90°+45°+x°=360°
225°+x°=360° add all of the values on the left side, then subtract 225 on both sides to solve for the value of x°.
x°=135°
We can simplify this equation using logaritmic rules. logx-logb = log(x/b)
than our equation becomes.
log3((18x^3)/(2x)) = log3(144) or
log3(9x^2) = log3(144)
for x= -4 we get that left side is equal to right side
log3(9*(-4)^2) = log3(144)
but if you put that value of x=-4 in start you will get log3(18(-4)^3) which is log of negative value which is imposible. That is why x=-4 is extraneous solution.
Common factor for 4 is 1, 2 and 4.
Common factor for 9 is 1, 3 and 9.
Both of these numbers only share 1.
3.56 kilograms of pears.
3/5 of 8.9 is 5.34
8.9 - 5.34 = 3.56
