I do not have an answer but you could always take an explanations how to do it easier. Hope it helps :)
Step-by-step explanation:
Example: solve √(2x+9) − 5 = 0
isolate the square root:
√(2x+9) = 5
square both sides:
2x+9 = 25
Now it should be easier to solve!
Move 9 to right:
2x = 25 − 9 = 16
Divide by 2:
x = 16/2 = 8
Answer:
x = 8
Check: √(2·8+9) − 5 = √(25) − 5 = 5 − 5 = 0
Given is rectangle with perimeter = 54 centimeters and area = 176 squared centimeters.
Let's consider the length of rectangle = L and width of rectangle = W.
We know the following formulas for rectangle :-
Perimeter = 2 x (L + W)
Area = L x W
So we have 2 x (L + W) = 54 and L x W = 176.
L + W = 27 and L x W = 176
We need to find two positive integers such that their sum is 27 and product is 176.
Using trial and error, we have two such positive integers such that 11 + 16 = 27 and 11 x 16 = 176.
So, the dimensions of rectangle would be 11cm x 16cm.
Hence, option A is correct i.e. 11 cm by 16 cm.
