x=46/5
Cross multiply, distribute the denominator, simplify by combining like terms, and isolate x.
Answer:
Step-by-step explanation: 10/2 = 5
20^2= x^2 + 5^2
400=x^2+25
x^2=375
x= 19.4
Positive Slope
<em>TIP for finding what slope it is:</em>
<em>Positive </em>- the line is pointing right
<em>Negative</em> - the line is pointing left
<em>Undefined </em>- the line is pointing up and down

Answer:
Step-by-step explanation:
Numbers 1 and 4 are perimeter questions so all you do is add up all the sides and the label is cm. For #2, this is an area problem and the area for a rectangle is length times width, so multiply the 2 together and the label is inches squared. For #3, the volume formula for a cube is side*side*side and the label for this is feet cubed. For #5, the area for a triangle is .5 times the base times the height, and the label is mm-squared. That should help you get all the answers on your wn. Very, very simple.
