Answer:
Width = 2
Length = 5
Step-by-step explanation:
let A be the area of the rectangle
L be the length of the rectangle
w be the width of the rectangle
<u><em>Formula</em></u>: ‘<u><em>area of a rectangle</em></u>’
A = L × w
…………………………………………………
A = L × w
⇔ 10 = (w + 3) × w
⇔ 10 = w² + 3w
⇔ w² + 3w - 10 = 0
<u><em>Solving the quadratic equation</em></u> w² + 3w - 10 = 0 :
Δ = 3² - 4(1)(-10) = 9 - (-40) = 9 + 40 = 49
then √Δ = 7


-5 is not valid ,because w represents the width
which must be a positive number
Then w = 2
<u><em>Conclusion</em></u>:
Width = 2
Length = 2 + 3 = 5
Answer:
A. horizontal reflection
Step-by-step explanation:
Given:


To identify the type of transformation.
Solution:
On close observation of the functions we find the that sign of
has changed in
with other terms being constant.
<em>Thus, the transformation statement can be given as:</em>

As:


The transformation
describes horizontal reflection of function across the y-axis.
Thus,
is horizontally reflected across y-axis to get
.
Greatest is number 8 and least is -11.
Easy, take your problem,
-5(a-6)+2a
Multiply the 5.
-5a+30+2a
Then just add apples and oranges.
-5a+2a= -3a.
Making your equation -3a+30.
Answer:
14x-56y-42
Step-by-step explanation:
Given data
We have the expression
7(2x - 8y - 6)
Open the bracket we have
14x-56y-42
Hence the equivalent expression is
14x-56y-42
