(5x^7y^2)(-4x^4y^5)=-20x^a y^b
<span>-20 x^11 y^7 = -20 x^a y^b </span>
<span>a = 11, b = 7 thus a: is you answer</span>
Answer:
34n=306
Step-by-step explanation:
Use inverse operation to find it, 306÷34= 9, check again 34(9)=306, so it's correct!
Answer:
P= 56
Step-by-step explanation:
Have a great day! ^w^
Answer:
first, subtract 17 on both sides: x²+2x-16=0
this cannot be factored, so use the quadratic formula to solve for x:
b²-4ac=2²-4(10(-16)=4+64=68
√68=2√17
so x=(-2+2√17)/2 or x=(-2-2√17)/2
x=-1+√17 or x=-1-√17
Step-by-step explanation:
4/5*75=60
ratio will be 24:36
