Answer:
72 cm
Step-by-step explanation:
You can solve this problem using the properties of the 45-45-90 right triangle. Assuming the 12 cm is a diagonal of the square, each side of the square can be modeled as x, and the diagonal will be x
.
This means 
, so 
.
Next, to find the area of the square you take the square of any of its sides. Since x is the length of one side, and , you can square 
to get the area. This is equal to 
or 72 cm.
First, square the entire problem. Then add the n's and subtract 10 from 5. You will then get 2n-5=0. Add 5 to both sides, then divide by two to get the answer. (2n=5, n=2.5)
F(x)=3x+18
That is the awnser they I got
Answer:
Are there two you're asking for?
#2: x ≥ 9
#3: x > -2
Step-by-step explanation:
#2 Work:
x - 13 ≥ -4
Step 1: Add 13 to both sides
x - 13 + 13 ≥ -4 + 13
Add -4 and 13 to get 9.
x ≥ 9
#3 Work:
x/2 > -1
Multiply both sides by 2. Since 2 is positive, the inequality direction remains the same
x/2 * 2 > -1 * 2
x > -2
Answer:
Mixed fraction = whole × denominator + numerator.
this formula converts mixed to improper fraction.
So, 1 × 3 + 1 = 4 is numerator.
Denominator is 3 which is same.
So, answer is
