Answer:
11
Step-by-step explanation:
<em>5+6=11</em>
X^2 + 14x + 45 = 0
(x + 5)(x + 9) = 0
x + 5 = 0
x = -5
x + 9 = 0 <=== here is the error...step 2
x = -9
Answer:
Use compatible numbers that are close to the actual numbers
Choose 36 for 35 3/4 and 6 for 5 7/8 because the divide evenly.
Step-by-step explanation:
Compatible numbers are numbers that are close to the actual values of a particular number. They make estimating easier when yo udo the different operations.
We choose 36 for 35 3/4 because 36 is closer to its value that 34. Conveniently, 5 7/8 is closer to 6 than 5, and they divide evenly. So a best estimate for the number of rows Holly can make would be:
36/6 = 6 rows.
Yes because it is linear, also if you set up the proportion 2/4=1/2 they are equal.
