Answer:
The correct answer of the problem is 1.
Step-by-step explanation:
Let the original number on which the wrong procedure is applied is x.
Now, Steve multiplied by 7 and then added 3 to get the answer of - 11.
So, 7x + 3 = - 11
⇒ 7x = - 14
⇒ x = - 2
Now, the correct step to get the answer is multiplying by 3 and adding 7.
Hence, the correct answer of the problem is (- 2) × 3 + 7 = - 6 + 7 = 1 (Answer)
Answer:
12 sides
Step-by-step explanation:
(n-2)*180/n = 150
180n-360 = 150n
-360 = 150n-180n
-(-360) = -(-30n)
360 = 30n
n = 360/30
n = 12
Answer:
A = 2x²; 128 ft²
Step-by-step explanation:
Area of original garden = x²
Let A = area of new garden. Then
A = 2x²
If x = 8 ft,
A = 2 × 8² = 2 × 64 = 128 ft²
The area of the new garden is 128 ft²
