Your "<span>h (x)=x 2 squared +6x-3" is ambiguous. If you meant "x squared," then you need only write x^2 OR "x squared," but NOT "x 2 squared."
I will assume that by "</span><span>h (x)=x 2 squared +6x-3" you actually meant:
</span><span>h(x)=x^2 +6x-3. To find h(3), subst. 3 for x: h(3) = (3)^2 + 6(3) - 3, or
h(3) = 9 + 18 - 3, or h(3) = 24.</span>
135000/6000=X
22.5=X
So this building would need 23 fire extinguishers <span />
(-infinity, 2]. Use the infinity symbol and not the word
32-n*470=? There’s 32 people and you subtract the n amount that couldn’t donate then multiply by 470
