Answer:
j= -4,6
Step-by-step explanation:
j^2 -2j -24 =0
Factor
What 2 numbers multiply to -24 and add to -2
-6*4 = -24
-6+4 = -2
(j-6) (j+4) =0
Using the zero product property
j-6 =0 j+4 =0
j =6 j=-4

Answer:
B = 2xy
Step-by-step explanation:
pretty sure this is it
Salut!
Ai ca a + b + c +d = 600;
a = b + 12 => b = a-12;
a = c - 12 => c = a + 12;
d = (a+b+c)/3 => d = a;
In final, 4a = 600 => a = 150;
b = 138;
c = 162;
d = 150;
Bafta!
Answer:
9pi approximately 28
Step-by-step explanation:
we have the formula - pi r^2
which we know the diameter is 6 m and the surface is a semi circle
the radius is 3 so then we have pi 3^2
which becomes 9pi which is about 28.2
rounding to 28
hope this helps!!
