Answer: D - 3 + 2√2 + √3
Solution: For the first question, we can just simply add up all of the terms to find the perimeter. Keep in mind that you cannot collect like terms for √3 and√2, since they are not alike. You have to keep them separate.
Hence, the only via solution is (D) 3 + 2√2 + √3
Answer: C - √10 + √13 = √23
Explanation: If we have two different terms inside the square root, we are not allowed to add them together; yes, you can multiply and divide, but not add or subtract.
For (A), if we square a number inside the root, we simply remove the square root sign, so that is correct.
For (B), we are allowed to multiply two square root numbers inside to form one unit.
For (D), we are allowed to divide two square root numbers inside to form one unit.
I think the answer is -2
Following the rule of “rise over run”, the fraction form of the gradient it 8 over 1 (8/1)
This means you move up 8 units, and move across 1 unit.
The final coordinate is (-1, -2)
V = -2
Hope this helps!
The fractions would be in order-
3/10, 1/2, 4/5
Because if you change each fraction to a denominator of 10, the numbers will be 3/10, 5/10, and 8/10
For the first question it is (3x-5) degrees second question is (x-5)
