Answer:
DE = 10
Step-by-step explanation:
Here, we want to find the value of DE
we use the intersecting chord principle
That will be;
CE * ED = AE * BE
we have;
6 * DE = 5 * 12
DE = (5 * 12)/6
DE = 5 * 2
DE = 10
15 x 10 is 150
600 - 150 is 450
Tommy still need 450 pencils
Hope this helps :)
Answer:
x = -2
Step-by-step explanation:
The root will touch the axis and bounce off when the exponent is even. In that case, that means (x + 2)² is the binomial that will bounce. Therefore, the root which bounces and touches the x-axis is x = -2.
Answer:
-4x+ 1/10
Step-by-step explanation:
−1/2x−1/5−5x+3/10+3/2x
Combine like terms
-1/2x -5x + 3/2x -1/5 + 3/10
Get a common denominator for each group
-1/2x -10/2x + 3/2x -2/10 + 3/10
-8x/2 + 1/10
Simplify
-4x + 1/10
-4x + 1/10
