0.5x7
Step-by-step explanation:
Assuming that the original expression is 
, according to PEMDAS multiplication takes priority over addition and subtraction,, and therefore, from the choices given, 0.5 * 7 must be performed first.
Step-by-step explanation:
So if you are reflecting across the x-axis then the point after the reflection should be (x,-y). If you are reflecting across the y-axis the the point after the reflection should be (-x,y). If you are reflecting across the line y=x, then the point after the reflection should be (y,x) If you are reflecting across the line y=-x, then the point after the reflection should be (-y, -x). If you are reflecting across the origin, then the point after the reflection should be(-x,-y). Hope this helps.
Answer:
2100 square cm
Step-by-step explanation:
To find the AREA of a three-dimensional, non-circular figure, you would want to multiply length by width by height ( 20 x 7 x 15). Since we're just looking for area and not volume, this is the equation we'll be going with.
20 x 7 x 15 = 2100
Add in the units, and we get 2100 square cm.
Hope I could help.
When we give x to second, then the third will be 2x and according to informations first one should be x-6. Then you have to sum all. It ll be equal to 4x-6.
78=4x-6
84=4x
21=x
So, first number is 15, second one is 21 and the last one is 42
