Make the equation:
To solve, add 136 to the other side and then divide by 2.
Answer:
The total surface area for the left block is 235.2
Step-by-step explanation:
multiply all the sides then add them together
Take the width to be 1.7 feet and the length to be (2.2 + 0.9) feet.
Then the area is (1.7 ft)(3.1 ft) = 5.27 ft^2 (answer)
Answer:
Step-by-step explanation:
Use the formula x-x1/x1-x2 = y-y1/y1-y2
Answer:
½Log 57 – ½Log 74
Step-by-step explanation:
Logb √(57/74)
We can expand the above expression as follow:
Logb √(57/74)
Logb √57 /√74
Recall:
logM/N = Log M – Log N
Therefore,
Logb √57/√74 = Logb √57 – Logb √74
Recall:
Log √M = Log M^1/2
Therefore,
Logb √57 = Logb 57^1/2
Logb √74 = Logb 74^1/2
Logb √57 – Logb √74 = Logb 57^1/2 – Logb 74^1/2
Recall:
Log M^1/2 = ½Log M
Therefore,
Logb 57^1/2 = ½Log 57
Logb 74^1/2 = ½Log 74
Logb 57^1/2 – Logb 74^1/2 = ½Log 57 – ½Log 74
From the illustrations above, we see that:
Logb √(57/74) = ½Log 57 – ½Log 74
