Ashley solves the equation

srry if this doesn't help

wut equation, is it:

Ashley solves the equation 0.4(2.5 x - 8) - 4 and claims that the solution is x - -0.8. The table below shows the steps she took and the reasons for each step.

Step 1

Equation

0.4(2.5 x-8)= -4

X-32=-4

x - 32+3.2 = -4 +32

x=-08

Reason

Given

Associative Property

Addition Property of Equality

Subtraction Property of Equality

Determine whether each statement below is true or false regarding the reasons given in the table. Select True or False for each statement.

True False

The reason for Step 1 is correct

The reason for Step 1 should be the Distributive Property

The reason for Step 2 is correct

The reason for Step 2 should be the Additive Identity Property

The reason for Step 3 is correct

The reason for Step 3 should be Additive Inverses Property and/or Combining Like Terms

Step-by-step explanation:

The reason for Step 1 is correct. False

The reason for Step 1 should be the Distributive Property. True

The reason for Step 2 is correct. True

The reason for Step 2 should be the Additive Identity Property. False

The reason for Step 3 is correct. False

The reason for Step 3 should be Additive Inverses Property and/or Combining Like Terms. True

Step-by-step explanation:

Distributive Property: a(b + c) = ab + ac

Addition property of equality: if x = y then x + a = y + a

Subtraction property of equality: if x = y then x - a = y - a

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
