Answer:
12, 17
Step-by-step explanation:
Two sides must add up to a greater sum than that of the remaining side
Well solve for x by simplifying both sides the isolating the variable to get x=5 for 2x-3 or x=2 for 2x+3
Answer:
x=4
Step-by-step explanation:
21x+6=90(alternate angles)
21x=90-6
x=94/21
Therefore, x=4
Answer:
C
Step-by-step explanation:
The diagonal can be represented as the hypotenuse of a right triangle with 3 and 3 as its legs. Use the pythagorean theorem to get that 3^2+3^2=c^2. Simplify to 9+9=c^2 or 18=c^2. Square root both sides to get c=√18. Simplify to get c=√9*2 or c=3√2 for the diagonal.
