The distributive property: a(b + c) = ab + ac
(x - 3)(4x + 2) = (x)(4x + 2) + (-3)(4x + 2)
= (x)(4x) + (x)(2) + (-3)(4x) + (-3)(2) = 4x² + 2x - 12x - 6
<h3>= 4x² - 10x - 6</h3>
Answer:
The height of the tree is about 30 feet.
Step-by-step explanation:
tan(55) = h/21
*21 *21
21*tan(55)=h
29.99=h
h=29.99=30 feet
Answer:
c = 208.8
Step-by-step explanation:
a. 
<em>To solve for C, you need to get the variable on one side of the equation and the numbers on the other side of the equation.</em>
b. <em>You need to move the 7.2 to the other side. So, </em><em>multiply</em><em> both sides by 7.2, because it's being divided, so multiplying will cancel it out.</em>
c: 
<em>Then, multiply 7.2 by 29. (The * symbol means multiply)</em>
d. c. = 208.8 <em>The answer is 208.8, which is rounded to the tenths place.</em>
Hope this helps! I tried to explain it in detail. :)
Answer:
234 inches
Step-by-step explanation:
Area= base x height
Height= 18 inches
Base= 13 inches
The height of a parallelogram must be perpendicular to its base, the base of this parallelogram can only be 13 inches and the height is 18 inches. Since the side lengths are not straight lines the height must be found using this method.
The height of a triangle, parallelogram and trapezoid must have a height that is perpendicular to its base. Whereas it can be found by extending the length of the base or straightening the side length that is to be the height creating a right angle.
What are the choices ? ? It's about 69 miles or 111 km.
