Answer:
55
Step-by-step explanation:
Step-by-step explanation:
an object and its shadow create a right-angled triangle.
2 objects and their shadows create 2 similar right-angled triangles.
that means the angles are the same, and the side lengths of one triangle all correlate with the corresponding side lengths of the other triangle via the same factor.
so,
42 × f = 6
f = 6/42 = 1/7
the length of Joel's shadow is then
20 × f = 20 × 1/7 = 2.857142857... ft
Answer:
5x^2 +10x
Step-by-step explanation:
The area is the product of the height and width. For this exercise, it is convenient to compute the rectangle areas individually, then write their sum:
blue rectangle area = (5x)(x) = 5x^2
red rectangle area = (5x)(2) = 10x
Total area = 5x^2 +10x.
_____
If you start by writing an expression for the total area, expanding it requires you deal with the unlike terms separately anyway:
5x(x +2) = 5x(x) +5x(2) = 5x^2 +10x
Answer:
Dependent Value: Cost (C)
Independent Value: Bushels (B)
Step-by-step explanation:
You can make the letter D out of the side of the bar graph and the letter I on the bottom, this tells you the label on the side is the dependent and the label on the bottom is the independent. If you dont have a line graph then think about this sentence starter: ...... effects.......

The answer would be 4c^2+8c+3
The arrow stands for squared off you didn’t already know but these are very easy to solve because you just multiply it out
