I hope this helps you
9x-x=35+109
8x=144
x=18
X-1/8=1/4
Add 1/8 for both side
x-1/8+1/8=1/4+1/8
x=1/4+1/8
1/4+1/8
=2/8+1/8
=3/8. As a result, x=3/8. Hope it help!
I would think 3? it should be 3 because 32*2=64 which isn’t everyone 32*3 is 96
79+12=91
2. 3/2x²
-1/2x²
1/4x²
5. -4x²-5 moves in 5 up on the y axis
6. I'm cant remember the trick to this one
7. This one should be D.
Hope This Helps!
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)
