Perimeter: 18.5 inches because to find the perimeter, you add all of the sides of the figure together, and 6+7.5+5=18.5
Area: 15 inches squared because the formula for the area of a triangle is: 1/2bh where b is the base and h is the height. So, 1/2(7.5)*(4) is 15
Answer:
No , (x-5) is not a factor
Step-by-step explanation:
x⁴ - 3x³ – 9x² - 4x = (x³ + 2x² + x + 1) (x - 5) <u>+ 5</u>

it is curved
Answer:
See below
Step-by-step explanation:
You will need a calculator for this
tan^-1 (-5.25) = -79.215 degrees
or 280.784 degrees
or 100.784 degrees
15 / 330 = 20 / x...15 gal. to 330 miles = 20 gal to x miles
cross multiply because this is a proportion
(15)(x) = (20)(330)
15x = 6600
x = 6600/15
x = 440 <=== 20 gallons will take u 440 miles
