Answer:
Step 2
Step-by-step explanation:
Meredith made a fatal mistake or error in step 2;
Any quadratic problem will always have two solutions. Therefore since, we only have one solution here, it is wrong. The mistake was incurred in step 2;
From the given problem ;
<u> Wrong right</u>
2(x + 4)² = 242
(x + 4)² = 121 Step 1
x+4=11 Step 2 x + 4 = ± 11
x = 7 Step 3 x + 4 = 11 or x + 4 = -11
x = 11- 4 or x = -11 - 4
x = 7 or -15
Answer:
Step-by-step explanation:
Diameter = 72 inches
radius r = 72/2 = 36 inches
Area = πr²
= 3.14* 36 * 36
=4069.44 inches²²
B: $8.75 :)))))))))))))))))))))
Answer:
135 days
Step-by-step explanation:
There are 100 numbers
There are 75 numbers greater than 25 (26-100)
P(number greater than 25) =
= number of numbers greater than 100/ total outcomes
= 75/100
=3/4
There are 180 days, so multiply the number of days by the probability
3/4*180 =135
The linear equation has an equal signed involved and the expression doesn’t.
