2x3 − 12x − 11
2x3 + 12x − 5
8x3 + 2x − 5
The sum of the polynomials are
To find the sum of polynomials we have to add like terms.
Like terms are those terms which have same variable with same exponent power.
Given polynomials are,

Using 1 can of paint 3 walls can be painted.
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Dan painted 3/4 of a wall using 1/4 of a can of paint.
So, 1/4 can used = 3/4 of wall
Then, in one can the amount of wall painted
= 3/4 x 4/1
= 3 walls.

Equation F: a = 3b + 4
Which statement describes a step that can be used to find the solution to the set of equations?
Equation F can be written as 5b + 1 = 3b + 4.
Equation F can be written as b + 1 = 3b + 4.
Equation F can be written as a = 3(a − 1) + 4.
Equation F can be written as a = 5(a − 4) + 1.
Answer:
Equation F can be written as 5b + 1 = 3b + 4
Step-by-step explanation:
A set of equations is given below:
Equation E: a = 5b + 1
Equation F: a = 3b + 4
In substitution method we solve the equation for a variable and substitute it in other equation
Given a= 5b +1
Also equation F : a= 3b+4
both equation have 'a' on the left hand side
So we substitute 5b+1 for 'a' in second equation
Substitute 5b+1 in the place of 'a' in Equation F
Equation F can be written as 5b + 1 = 3b + 4
