The person above me is correct
Expression (non-algebraic): 3+2
An equation: 2x +1 = 21
An inequality: 2x > 2+2
To find this I would use the pythagorean theorem which is:
a^2 + b^2 = c^2
Since we already know c = hypotenuse, and a side of the shorter sides we can plug them it like this:
11^2 + b^2 = 12^2
121 + b^2 = 144
b^2 = 23
√23 = 4.79
Round:
B. 4.8 would be your answer!
Answer:
yes
Step-by-step explanation:
42/54 = 6*7/6*9 = 7/9
7/9 = 42/54
The best estimate of the lateral area of the cube with edges that are 2.1 inches long is 4.2
