Second answer: f - 52 = 63.
The value of constant a is -5
Further explanation:
We will use the comparison of co-efficient method for finding the value of a
So,
Given
As it is given that
(x^2 - 3x + 4)(2x^2 +ax + 7) = 2x^4 -11x^3 +30x^2 -41x +28
In this case, co-efficient of variables will be equal, so we can compare the coefficients of x^3, x^2 or x
Comparing coefficient of x^3
So the value of constant a is -5

Answer:
7.5
Step-by-step explanation:
you take the largest number (9.8) and subtract with the smallest number (2.3)
<h2>9.8-2.3= 7.5</h2>
Answer:

San Antonio 5
Answer: 23
Step-by-step explanation:
Benches = x
4x + 3 = 5x - 2
x = 5
this equals that x = 5 because we put the unknown algebraic number on one side and the numerals on the other.
So if there are 5 benches then the number of children will be
4 * 5 + 3 or 5 * 5 - 2, which both equal 23.
Therefore, the answer to this question is 23 children
