Answer:
-12x + 4
Step-by-step explanation:
(6x - 8 - 2x) - (12x - 7) - (4x - 5)
The subtraction sign before the parenthesis is basically multiplying by -1, so the subtraction signs in the parenthesis have to change to addition. After that, you can remove the parenthesis.
6x - 8 - 2x - 12x + 7 - 4x + 5
Simplified = -12x + 4
Answer:
Distance travelled by Monarch butterfly = 2000 miles
Distance travelled by desert locust = 2800
Distance travelled by pink-spotted hawk moth= 7800 miles
Step-by-step explanation:
Let the distance travelled by Monarch butterfly be "X" miles
Distance travelled by desert locust is equal to X + 800 miles
Distance travelled by pink-spotted hawk moth is equal to 4X -200 miles
The total distance travelled by the three is equal to 12600 miles
Distance travelled by Monarch butterfly = 2000 miles
Distance travelled by desert locust = 2000 + 800 = 2800
Distance travelled by pink-spotted hawk moth = 4 * 2000 -200 = 7800 miles
Answer:
Step-by-step explanation: 6
Answer:
-3x^2 +4x -15 +25/(x+1)
Step-by-step explanation:
The synthetic division is shown in the attachment. The coefficients in your given expression are out of order, so need to be rearranged for division by most manual methods.
In binary tree there are
n ancestor at level n.
Proof :
Take P(0): At node level
0, it has no ancestors since this is a roo tnode.
Take P(1): At node level
1, it has one ancestor. The ancestor is the root, its parents which is at level
0.
Take P(K): A node level
K it has K ancestors. Its parent is at level K – 1.
Take P(K+1): At node K +
1 level have more than one ancestor than that of node at k level.
<span>Thus there are n ancestor
at level n in binary tree.</span>
