Answer:
(a+b)(a-b)-19
Step-by-step explanation:
a²-b²
=a²-ab+ab-b²
=a(a-b)+b(a-b)
=(a+b)(a-b)
it'll be more easy to understand if u try solving it the other way(from bottom to the top)
there fore... a²-b²=(a+b)(a-b)
and -20+1=-19
so then the ans will be(a+b)(a-b)-19

The length of a board is 2 5/8 feet long . Of 5/6 of a foot is trimmed off ,find the new length
Answer:
I think it is 25 ft and 10 in
Step-by-step explanation:
BTW i'm probably wrong because my mom says i suck at math but friend me please lol
Answer: 1 19/24 ft
Step-by-step explanation: You multiply the fractions by the numbers needed to get the common denominator of 24 in this case 5/8 (put the two to the side for now.) multiply both top and bottom by 3 which will get you 15/24 then the whole number 2, your going to take it and subtract one from it so now there is only one whole number then with the one you subtracted you multiply (1x24)+15 *for the numerator* so now its 39/24 and for the second fraction 5/6 multiply both top and bottom by 4 now your fraction is 20/24 now...--> 39/24 - 20/24=19/24 and the left over whole number from the beginning goes down in front so the final answer is 1 19/24

SIMPLE QUESTION, 25 PTS: The cities G, H, and I, in respective order, lie approximately in a straight line. The distance from city G to city H is 72 miles. The distance from city G to city I is 92 miles. Find the distance from city H to city I.
Hey there! I'm happy to help!
From G to I is the total distance of the line (92). G to H is the first portion of the line (72) while H to I is the other portion.
To find H to I, simply subtract 72 from 92!
92-72=20
The distance from city H to city I is 20 miles.

What is another name for line m in the figure below
Answer:
TV or VT
Step-by-step explanation:
A line is defined by the two points lying on an infinitely long straight paths.
From the picture attached,
There are two endless paths 'l' and 'm' which contain (R, U) and (V, T), intersecting at a point S.
Therefore, line 'm' will be represented by VT or TV.
And line 'l' will be represented by RU or UR.

Perimeter of rectangle = 26
Length is 7 less than 9 times the width.
We have to find the width of rectangle[tex].[/tex]
_________________________________
Let, width of rectangle be x therefore length of rectangle will be (9x - 7)
We know that, perimeter of rectangle is given by
perimeter = 2 (length + width)⇒ perimeter = 2 (l + b)
⇒ 26 = 2 [(9x - 7) + x]
⇒ 13 = x + 9x - 7
⇒ 20 = 10x
⇒ x = 2 (width)
Cheers!Step-by-step explanation:
Let breadth be x
As it is given that, the Length is 7 less than 9 times :
Therefore, Length will be 9x - 7
Perimeter of reactangle = 26
➳ 2 ( Length + Breadth) = 26
➳ 9x - 7 + x = 26/2
➳ 10x = 13 + 7
➳ 10x = 20
➳ x = 2
Therefore,
Breadth = x = 2 Length = 9x - 7 = 9(2) - 7 = 11can someone help pls 20 points

What is equation?Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.
2x – 1 + 3x = 0
5x – 1 = 0
To get Equation B from A, we would rewrite one side (or both) by combining like terms
2x – 1 + 3x = 0
5x – 1 = 0
This is Equation B

Brad says that the literal equation a = 3b + 4c - a is solved for a. Do you agree yes or no?
Answer:
No
Step-by-step explanation:
The literal equation a = 3b + 4c - a contain "a" on the right side so it is not solved for a.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
If we solve any equation for x then
x = f(other than x)
For example
x + 2x + 3y = 4
Solve for x will be
3x + 3y = 4
x = (4 - 3y)/3 so on right-hand side no x term is present.
Given the equation,
a = 3b + 4c - a
The right-hand side has termed "a" so it is not solved for a.
Hence "The literal equation a = 3b + 4c - a contain "a" on the right side so it is not solved for a".

Differentiate y=(sinx)(3x^2) please help please !
Answer:
6xsinx + 3x²cosx
Step-by-step explanation:
Differentiate using the product rule
Given y = f(x)(g(x) , then
[tex]\frac{dy}{dx}[/tex] = f(x)g'(x) + g(x)f'(x)
Here f(x) = sinx ⇒ f'(x) = cosx
g(x) = 3x² ⇒ g'(x) = 6x
Thus
[tex]\frac{dy}{dx}[/tex] = 6xsinx + 3x²cosx
