Below are the steps to solve an equation: Step 1: |x − 4| + 1 = 8 Step 2: |x − 4| = 8 − 1 Step 3: |x − 4| = 7 Which of the following is a correct next step to solve the equation? (1 point) x − 4 = −7 x + 4 = −7 −x − 4 = 7 x + 4 = 7

answer: i don't understand. what are the options

step-by-step explanation:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
