Answer:
The sum is a binomial of degree 3.
Step-by-step explanation:
You are adding two binomials. Each binomial has two terms.
The terms 6s^2t and 4s^2t are like terms and combine to give the sum 10s^2t.
The terms -2st^2 and -3st^2 are like terms and combine to give the sum -5st^2.
The sum of the binomials is the binomial 10s^2t - 5st^2.
Since each original binomial is of degree 3, the sum is also of degree 3.
Answer: The sum is a binomial of degree 3.
Answer:
x = 55 or x = 15
Step-by-step explanation:
Solve Absolute Value.
We know that either 1/5x - 7 = 4 or 1/5x - 7 = -4.
1/5x - 7 = 4
1/5x - 7 + 7 = 4 + 7
1/5x = 11
1/5x (5) = 11 (5)
x = 55 (one possibility)
1/5x - 7 = -4
1/5x - 7 + 7 = -4 + 7
1/5x = 3
1/5x (5) = 3 (5)
x = 15 (second possibility)
Answer:
Step-by-step explanation:
A = (7 + 4)(24) ÷ 2 = 132 units²
