Answer:
side CB
Step-by-step explanation:
draw triangles ABC and ACD next to each other
The longer leg of the triangle ABC is CB, which corresponds with the longest leg of ACD, which is side CD
Answer:
y-1=2/3(x+6)
Step-by-step explanation:
point slope is y-y sub 1=m(x-x sub one)
Plug in m and the point to get point slope
Answer:
<u>Let's verify is the corresponding sides have same ratio:</u>
- ΔABC, sides: 6, 9, 11
- ΔXYZ, sides: 21, 31.5, 38.5
<u>Ratios:</u>
- 6/21 = 2/7 (divide by 3)
- 9/31.5 = 2/ 7 (divide by 4.5)
- 11/38.5 = 2/7 (divide by 5.5)
The ratios are same, so the triangles <u>are similar</u>
- Yes, the sides are all proportional
The scale factor (ΔABC to ΔXYZ) is <u>2/7</u> (or ΔXYZ to ΔABC is 7/2 = <u>3.5</u>)
Answer:
17xy + 16yz
Step-by-step explanation:
Rearrange so that like terms are together and add them up.
8xy + 9xy + 6yz + 10yz
17xy + 16yz
