Idk if you have any choices or not but it should look like 8 + 2x
How to get the answer: sum means addition, and twice a number is 2 times it. We don't know the number so we'll use x. Two times a number is 2x
And since we are adding we will put an addition sign
8 + 2x
Answer:
60°, 120°, 180°, 240° and 300°
Step-by-step explanation:
In case of a regular hexagon, there is a set of six movements to complete its one rotation. Now in one rotation, it will complete 360° of its circular motion. Now the formula to calculate the angle of rotation for any shape with equal length of its sides is:
Angle of rotation (Ф) = 360/Total number of sides
In this case, Ф = 360/6
Ф = 60
This formula is valid for every shape with equal sides, like in case of pentagon you will have 360/5 to calculate the angle of rotation.
Now in case of hexagon, at rotation of 60°, its rotation is symmetrical, which means rotation will not change its physical appearance, this is the case for next 60° rotation as well, or you can say that for 120° (60° before and 60° afterwards). This suit will follow for all the angles given in the answer section.
Answer with explanation:
Two Quadratic expressions are said to be equivalent,if they have same zeroes.But here it has been asked about ,expression which are of the same form,means Instead of being congruent they should be similar.
Expression Equivalent Expression
1. x²+ 3 x + 15 ---------------------- x² + 6 x + 34
2. x² + 8 --------------------- x² + 16
3. x² - 5 x + 5 -------------- x² -12 x + 37
Answer:
looks like C is best guess
