Answer:
(4x + 3) + (-2x + 4) = 2x + 7
Step-by-step explanation:
(4x + 3) + (-2x + 4) = you then collect like terms
(4x + -2x) + (3 + 4)= like this, and you add what's inside perenthesis
= 2x + (3 + 4). step-by-step
= 2x + 7. then that is how you get =2x+7

explanation: This is the edmentum answer
Answer:
D
Step-by-step explanation:
The degree of a polynomial is determined by the largest exponent of a term within the polynomial.
Given
7x³ + 4x - 5 + 8
The term with the largest exponent is 8 with exponent 5
Thus the polynomial is of degree 5 → D
Answer:
5P5×20P15
Step-by-step explanation:
A school bus has 25 seats, with 5 rows of 5 seats.
15 students from the first grade and 5 students from the second grade travel in the bus.
second-grade students occupy the first row.
The 5 students of second grade are to be seated in 5 seats,this can be done in:
5P5 ways where P is the permutation
Now 15 students from first grade are to be arranged in remaining 20 seats
This can be done in:
20P15 ways
Hence, total ways student can be seated is:
5P5×20P15
Answer:
Independent event
Step-by-step explanation:
We have different type of event occurrence: an event could be dependent, independent or mutually exclusive.
Two event are mutually exclusive if disjoint if they cannot both occur at the same time. An example of mutually exclusive event is the set of outcomes of a single coin toss, which can result in either heads or tails, but not both.
Two events are independent if the occurrence of one does not affect the probability of occurrence of the other. Independent Events are not affected by previous events.
Two events are dependent if the occurrence of one does affect the occurrence of the second one.
