Answer:
triangle ABC is "not" a right-angled triangle
Step-by-step explanation:
AB=8cm
BC=5cm
perimeter = 22cm
CA = 22 - 8 - 5 = 9
8² + 5² = 89
9² = 81
AB² + BC² ≠ CA²
Answer: This is False because they don't go together and it doesn't make sense.
Step-by-step explanation:
Standard deviation I think

Answer:
2x+5 r. 13
Step-by-step explanation:
So using long division, you can solve for the quotient and the remainder.
Please look at the attached for the solution.
Step 1: need to make sure that you right the terms in descending order. (If there are missing terms in between, you need to fill them out with a zero so you won't have a problem with spacing)
Step 2: Divide the highest term in the dividend, by the highest term in the divisor.
Step 3: Multiply your result with the divisor and and write it below the dividend, aligning it with its matched term.
Step 4: Subtract and bring down the next term.
Repeat the steps until you cannot divide any further. If you have left-overs that is your remained.
