How would you solve (4k+5)(k+1)=0?
Answers
Before you rush off and start trying to do complicated things with that equation,
put your pencil down, fold your hands in your lap, and sit and look at it for a while.
Keep looking at it until a little voice yells out "Hey ! That's a true statement if
either (4k + 5) is zero or (k+1) is zero. THEN go to work on it.
(4k + 5 = 0)
4k = -5
k = -5/4
(k + 1 = 0)
k = -1
And there are the two solutions to that equation.

By plotting the given points on the coordinate plane ( shown below )
We get a rectangle.
Suppose ABCD is a rectangle such that,
A≡(-1,1), B≡(3,1), D≡(3,-4) and C≡(-1,-4),
By the distance formula,
∵ Perimeter of a rectangle = 2 ( sum of any two adjacent sides )
Thus, the perimeter of the rectangle ABCD = 2(AB + BC)
= 2(4+5)

Slope is -2/5 and y-intercept is 2
Step-by-step explanation:
- Step 1: Write the equation in slope-intercept form y = mx + b
2x + 5y = 10
5y = -2x + 10
y = -2/5 x + 10/5
y = -2/5 x + 2
- Step 2: Find the slope and y-intercept from the equation.
Slope, m = -2/5
y-intercept, b = 2

Some of the fractions that are equivalent to 4/7 are 8/14, 12/21, 16/28, 20/35 e.t.c
What is equivalent expression?
Equivalentexpressions are expressions that work the same even though they look different.
If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
For example , 5 × 4 = 20 and 2 × 10 = 20 , so the two expressions are equivalent and they have thesame value
To find the equivalent of 4/7, we can multiply through by a factor of 2, 3 , 4 ,5 e.t.c
Therefore 4/7 = 8/14 = 12/21 = 16/28 = 20/35
