Are these right? How do the parentheses make these two answers different?

yes it is correct

with parentheses you have to bring EVERYTHING INSIDE THE PARENTHESES to the given power but not if there are no parentheses

I know someone already answered this but they would be correct. This is how I think of it... if it does not have parentheses and it is a negative number and it has an exponent well then your answer will be negative but if you do have parentheses and your number is negative and it has an exponent well then your answer will be positive.

2(2x − 1) > 6  or  x + 3 ≤ −6


2(2x − 1) > 6

4x - 2 > 6

4x > 8

x > 2

or

x + 3 ≤ −6

x ≤ - 9

Solution: x ≤ - 9 or x > 2

(- ∞ , - 9] or (2 , + ∞)

Answer is the first one

(- ∞ , - 9] or (2 , + ∞)

Happy New Year from MrBillDoesMath!

Answer:

Proof by ASA congruence postulate. See below

Discussion:

  Fact 1 :     angle A = angle T             (given)

  Fact 2:    The angles on both sides of point X are equal as vertical angles

                 are equal.

From these facts it follows that angle M = angle H (as all plane triangles have 180 degrees). Also  AM = TH  (given) so

   In the left triangle                          In the right triangle

  (angle M, side AM, angle A)  =      (angle H, side TH, angle T)


Hence the triangles have two congruent angles, and congruent sides included between the angles, so they are congruent by  ASA.


Thank you,

MrB

Answer:

The Answer is: Perimeter = 39.12

Step-by-step explanation:

Given: area is 56.96 m^2

Given: length is 16m.

Find Width.

Equation:

Length x Width = Area

Solve for Width, w.

16 x w = 56.96

w = 56.96/16 = 3.56.

Perimeter all the sides added together:

P= 2l + 2w

= 2(16) + 2(3.56)

= 32 + 7.12

= 39.12 m, perimeter

Hope this Helps!! Have an Awesome Day!! (-:

Ed plants trees in city parks. He used 1\10 of a bag of fertilizer around the base of a newly planted tree. How many trees can E
valina [46]
To determine this you could think of it in a couple ways.

1. If it takes 1/10 of a bag of fertilizer to put around 1 tree, he can fertilize 10 trees with 1 bag because there are 10 groups of 1/10 in a bag. Take 10 x 40 because there are 40 bags and get 400 trees to be fertilized.

2. You can divide 40 by 1/10 as the other strategy.
This is the same as 40 x 10/1.

Also equaling 400 trees that can be fertilized.
