Choose the correct item from each drop-down menu to factor the trinomial 3x2 + 13x – 10 by grouping.
Answers
The factors of the given trinomial are (3x-2)(x+5).
What is trinomial?Trinomial is a polynomial having 3 terms. At least one variable and one operation (addition, subtraction, multiplication, division) must be present in an algebraic expression.
Given is a trinomial 3x²+13x-10, we need to factorize it,
So,
= 3x²+13x-10
To factorize a trinomial, we do find the product of the product of a and c (ax²+bx-c) and find its two factors so that we can add or subtract so that we can find the middle term (b) of the trinomial,
Here,
a = 3, c = 10
a × c = 30
Now,
15 and 2 are the factors of the 30, also 15 - 12 = 13 which is the middle term of the trinomial,
Therefore,
3x²+13x-10 = 3x²+15x-2x-10
= 3x(x+5)-2(x+5)
= (3x-2)(x+5)
Hence, the factors of the given trinomial are (3x-2)(x+5).

Answer:
Step-by-step explanation:
∠5 = ∠1 {Alternate exterior angles are congruent}
8x - 19 = 7x - 3
Add 19 to both sides
8x = 7x - 3 + 19
8x = 7x + 16
Subtract 7x from both sides
8x - 7x = 16
x = 16
∠5 = 8x - 19
= 8*16 - 19
= 128 - 19
∠5 = 109
∠5 + ∠4 = 180 {linear pair]
109 + ∠4 = 180
∠4 = 180 - 109
∠4 = 71°

how to use union in the real world?
Answers
Answer:
To overcome such type of real world problems we use union. Unlike structures union occupies single memory location to store all its members. So, unions are helpful when you want to store value in single member from a set of members. Size of union is defined according to size of largest member data type.
Step-by-step explanation:
In union, all members share the same memory location. For example in the following C program, both x and y share the same location. If we change x, we can see the changes being reflected in y. #include <stdio.h> // Declaration of union is same as structures.

5x+4=5x+4 is it one solution, no solution, or infinite solutions?
Answers
Simplifying
5x + 4 = 5x + 4
Reorder the terms:
4 + 5x = 5x + 4
Reorder the terms:
4 + 5x = 4 + 5x
Add '-4' to each side of the equation.
4 + -4 + 5x = 4 + -4 + 5x
Combine like terms: 4 + -4 = 0
0 + 5x = 4 + -4 + 5x
5x = 4 + -4 + 5x
Combine like terms: 4 + -4 = 0
5x = 0 + 5x
5x = 5x
Add '-5x' to each side of the equation.
5x + -5x = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 0
Solving
0 = 0
Couldn't find a variable to solve for.
This equation is an identity, all real numbers are solutions.
Infinite solutions
Try to solve this equation:
5x+4=5x+4
Move all the variables to the left:
5x-5x+4=4
Do you see what I see?
4=4
We end up with a true statement. 4 does indeed equal 4. Hope this helps!
