It is (1,15). I recommend using a website called desmos because it helps with graphing.
Answer:
Step-by-step explanation:
<span>(5x^7 y^2)(-4x^4 y^5) =-20x^a y^b
</span><span>
solve this:
(5x^7 y^2)(-4x^4 y^5)
= -20 x^(7 + 4) y^(2 + 5)
= -20 x^11 y^7
answer
</span>A) a=11, b=7
Yes. A triangle with three sides given can be cut out.
