If b>a, b-a=5 so b=5+a
ab=126, using b from above
a(5+a)=126
5a+a^2=126
a^2+5a-126=0
(a+14)(a-9)=0, since a<0 the numbers are
-14 and -9
Answer:
n/-5 - 9 = 2
Should be the correct answer.
Answer: y= 66
Step-by-step explanation: Well first you would do +7 on both sides and then it would be Y/6=4+7, then you would multiply 6 on both sides which then you would have y=24+42 which simplified it would be y=66
<span><span /><span>In an observational study, During the discussion,
the author can indicates conclusion and explains the limitation of the study he

can write when , where and how he did his research and in result is where he
can state what problem his research answered or what’s the edge of his

Answer:
B. 2x + 4y
Step-by-step explanation:
If x = 4, and y = 7, let's substitute these values for x and y in the equations!
For A, the equation is 2xy. Substitute the values and you have 2(4)(7) which equals 56. This expression is incorrect since the expression doesn't equal 36.
For B, the equation is 2x + 4y. Substitute and you get the equation
2(4) + 4(7) → 8 + 28 = 36.
36 is your desired value, and you get that with the expression 2x + 4y.
