The equivalent expression is
Step-by-step explanation:
The distributive property says for any numbers <em>a, b c</em>, and <em>d</em>
which basically says you should multiply the coefficient by every term in the parenthesis to get an equivalent expression.
Applying the distributive proper to the expression we get:
which is an equivalent expression to .
Answer:
The base of the ladder has a length of 8 ft.
Step-by-step explanation:
We have to draw a triangle, as the figure attached.
The hypothenuse of the triangle is the length of the ladder (17 ft).
The height on the wall that the ladder reach is the adjacent (15 ft).
The base of the ladder is our unknown quantity X.
We will use the Pythagorean theorem to express the relation between these numbers:
The base of the ladder has a length of 8 ft.
True, y=7 means its just a horizontal line running straight through the 7 on the vertical/y-axis.
