Answer:
Step-by-step explanation:
in a right triangle a^2+b^2=c^2,
where a and b are the legs
where c is the hypothenuse
9^2= b^2+3^2
81-9=b^2
b^2=72
b=8.48
<span>17.2 + 6.08+0+0+0+0+0+0+0+0= 23.28.</span>
Answer:
7-(-4)= Positive
-3+(-2)= Negative
5-8= Negative
-10 +12= Positive
Step-by-step explanation:
<span>Factor completely: 3x2 + 9x − 3
</span><span>3x2 + 9x − 3 (a 3 can be divided from each number)
</span>3(x2+3x-1)
can <span>x2+3x-1 be factored out anymore? <span>no
</span></span><span>3(x2+3x-1) is the answer</span><span>
</span>
$11 because you add the 2 and then divide by 3 and 18 plus 15 is 33 and 33 divided by 3 is 11
