Answer:
24.997 = 25.00 (rounded off to 2 decimal figures)
Step-by-step explanation:
By observation, we can see that both straight lines are of equal length and that the angle between the lines is 90°. Hence we can conclude that this is a quadrant of a circle with radius, r = 7 cm.
length of the curved section
= 1/4 x circumference of the circle
= 1/4 x 2πr
= 1/4 x 2 x 3.142 x 7
= 10.997 cm²
HEnce circumference = 10.997 + 7 + 7 = 24.997 = 25.00 (rounded off to 2 decimal figures)
Answer: −22
Step-by-step explanation:
=−14−8
=−14+−8
=−22
On both sides of the equal sign you subtract b (-b) which would give you -b+y=2x after that you subtract a y (-y) which gives you -b=2x-y now I was taught that you can't have a negative letter equal something so you change all of the signs to the opposite which would give you b=-2x+y
