Answer:
16 children
Step-by-step explanation:
80% of 20 children comes out to 16 children who are of age 5.
If desired, rewrite "80%" as "0.80" and use that 0.80 as the multiplier of 20:
0.80(20 children) = 16 children.
C: Bc 3 * c = 3c (plus 7 more) = 7+3c
The answer to this question should be 114
Answer:
Step-by-step explanation:
First Question: Equilateral triangles all have the same interior angles. 60 degrees. Size does not make the angles bigger. It makes the sides bigger.
Second Question: No the size does not influence the size of the interior angle.
Third Question: That's true for all polygons. Size is not affect the interior angle size.
X^2 - 13 x = -36
add 36 to both sides
x^2 - 13x +36 = 0
figure out the factor
(x-4)(x-9) = 0
so (x-4) or (x-9) equals 0
so solution is
x-4=0 add 4 to both sides and get x = 4
x-9=0 add 9 to both sides and get x=9
x={ 4, 9}
