11
Step-by-step explanation:
-(-7)^2 + (6*-7) + 4
7^2 + (-42) + 4
49 - 42 + 4 = 11
Answer:
From these number, only 12,15 and 21 can be represented by a product of two one-digit number
<em>1/6 = 0.16 acres in 8 minutes. </em>
<em>--</em>
<em>0.16 ÷ 8 = 0.02 acres mowed in 1 minute.</em>
<em>--</em>
<em>(60 minutes in an hour)</em>
<em>0.02 x 60 = 1.2 acres mowed in an hour.</em>
<em>-- </em>
<em>1.2 is equal to 1 1/5, and jami needs to mow 1 1/2 acres.</em><em> so no, jami cannot mow 1 1/2 acres in an hour.</em>
A) 2x+1+16/(x+4) is correct
length × width = Area of rectangle
length=Area/ width
(2x²+9x+20)/(x+4)= length
length= to the above answer
