Answer:
Step-by-step explanation:
I think you are to assume that this is a trapezoid and that the top right angle symbol is missing.
Area = (b1 + b2 ) * h /2
Givens
b1 = 2
b2 = 6.2
h = 3
Solution
Area = (2 + 6.2)* 3 / 2 Combine what is inside the brackets
Area = 8.2 * 3 / 2 Divide by 2
Area = 4.1 * 3 Combine
Answer: Area = 12.3
Answer:
18x + 16
Step-by-step explanation:
2 x length + 2 x width = perimeter
2(5x + 2) + 2(4x + 6)
= 10x + 4 + 8x + 12
= 18x + 16
Answer:
Step-by-step explanation:
Let x represent the number of hours that he works. babysitting his neighbors children.
Let y represent the number of hours that he works at the other job.
He earns $10 per hour babysitting his neighbors children. This means that the amount that he earns, babysitting his neighbors children for x hours would be
10x
He earns $12 per hour working at the other job. This means that the amount that he earns, working at the other job for y hours would be
12y
Therefore, the inequality that represent the number of hours that he needs to work at both jobs to earn a minimum of $120 is
10x + 12y ≥ 120

Step-by-step explanation:
The vertex form looks like y-k = a(x-h)^2. We must re-write y = 2x^2 + 16x + 17 in this vertex form.
Note that y = 2x^2 + 16 x + 17 can be re-written as y = 2(x^2 + 8x) + 17
Let's complete the square: to x^2 + 8x add 4^2, and then subtract 4^2:
y = 2(x^2 + 8x + 16 - 16) + 17. This become y = 2(x^2 + 8x + 16) + 1, or
y = 2(x+4)^2 + 1 (answer), or y - 1 = 2(x-[-4])^2 + 1. The vertex is
at (-4, 1).
