Question 10: P=28cm
if l=8 and w=6
Then (8+6)=14
2(14) so 14x2 = 28
So therefore P=28cm
Answer: 95 units squared
Step-by-step explanation:
Rectangle of 10*4=40
Rectangle of 5*7=35
Triangle of 4*10/2=20
40+20+35=95
Answer:
Step-by-step explanation:
(40,5) and (0,0) are points on the line.
Slope of line = (40 miles)/(5 minutes) = 8 Mikes per minute
If you mean distance, then we can use the distance formula to find out.
(x - x)² + (y - y)² = d² Distance formula
(-2 + 2)² + (7 + 6)² = d² Substitute the points; remember that when you subtract a negative, you add, and also remember to always subtract in the same direction (with the points (1,2) and (3,4), if you do 1 - 3, then do 2 - 4 and not 4 - 2)
(0)² + (13)² = d² Add
0 + 169 = d² Square
169 = d² Add
13 = d Take the square root of both sides to cancel out the exponent
The distance between (-2,7) and (-2,-6) is 13 units.
Hope this helps!
