There are a total of 900 students at Molly’s school. 810 is 90% of 900. 90% of students did not wear a silly hat.
Answer:
The factors of x^3+2x^2+5x+10 are (x^2+5)(x+2)
Step-by-step explanation:
x^3+2x^2+5x+10
Group the expression by two:
=(x^3+2x^2)+(5x+10)
Factor out GCF in each group.
=x^2(x+2)+5(x+2)
Note:(The binomials in parentheses should be the same, if not the same... there is an error in the factoring or the expression can not be factored.)
Now factoring out the GCF which basically has you rewrite what is in parentheses and place other terms left together:
=(x^2+5)(x+2)
Thus the factors of x^3+2x^2+5x+10 are (x^2+5)(x+2)....
Different ways to make the number 15,638 with
hundreds, tens and ones are: <span>
156 hundreds, 3 tens and 8 ones
150 hundreds, 63 tens and 8 ones
141 hundreds, 161 tens and 28 ones
<span>we can write the numbers in thousands, hundreds, tens and ones
by using the place values. We use these ten numbers 0,1,2,3,4,5,6,7,8,9 along
with the concept of place value.</span></span>
They are usually represented like this
commutative property of addition
a+b=b+a
associative property of additon
(a+b)+c=a+(b+c)
identity property of addition
a+0=a
so number sentatnces
lets say a=1,b=2,c=3
commutative property of addition
1+2=2+1
associative property of addition
(1+2)+3=1+(2+3)
identity property of addition
1+0=1
