Answer:
~A-------------> ~B
Step-by-step explanation:
Let "if i do my homework be (A)" and "then it will snow be (B)"
Inverse of A and B
~A implies ~B
~A --------------> ~B
"if i do not do my homework, then it will not snow".
Answer:
X=3
Step-by-step explanation:
9+x=12
x=12-9
so x is 3
The <em>correct answers</em> are:
B) ∠R is congruent to ∠C; C) ∠B is congruent to ∠Q; E) BC is congruent to QR.
Explanation:
Using the congruence statement, we can state that corresponding elements of the triangles are congruent. In the statement, ∠R matches ∠C; ∠B matches ∠Q, and side BC matches side QR.
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.
