Answer:
1. 25
2. 10
3. 250
Step-by-step explanation:
Distance formula :√ (x2 - x1)² + (y2 - y1)² √ ()² + ()²
1. LENGTH OF AB :
A = 15,18
B = -5,3
√ (-5 - 15)² + (3 - 18)²
= √ 400 + 225
= 25
2. LENGTH OF AD :
A = 15,18
D = 21,10
√ (21 - 15)² + (10 - 18)²
= √36 + 64
= 10
AREA :
A=w x l
10 x25 = 250
Answer:
not proportional
Step-by-step explanation:
Answer: x^2+3x+2
Step-by-step explanation:
This can be factored as (x+2) (x+1) and i know it’s in standard form because it goes from highest degree to lowest.
Answer:
10.8
Step-by-step explanation:
3^0=1
2*1=2
23.6-2=21.6
21.6/2=10.8
<span>The problem says that Donovan is using similar rectangles, so you can calculate the length of the second rectangle, by using the similarity concept.
We have that the first rectangle </span>is 2 inches wide and 6 inches long, and the second rectangle must has<span> 5 inches wide. Then:
2/5=6/L (L: </span>the length of the second rectangle).
<span> 2L=6x5
2L=30
L=30/2
L=15 inches
H</span><span>ow long must the second rectangle be?
</span><span>
The answer is: The second rectangle must be 15 inches long.
