Answer:
yes
Step-by-step explanation:
cross-products both equal 180
20(9) = 10(18)
180 = 180
Answer:
a=7b=9c=4
Step-by-step explanation:
3^x - 7 = 7
Add 7 to both sides:
3^x = 14
Use the natural log on both sides:
x = ln(14) / ln(3)
x = 2.4022
Round the answer as needed.
Answer:
21, 35 , 49
Step-by-step explanation:
21 = 3 * 7
35 = 5 * 7
49 = 7 * 7
GCF = 7
Given vertices of parallelogram ABCD:
A(−10,6), B(−5.5,26), C(9.5,18), and D(5,−2).
<u>Length of AB is :</u>
.
<u>Length of BC is : </u>
Note, opposite sides of a parallelogram are equal.
Therefore,
<em>Perimeter of parallelogram ABCD = 2 × Length of AB + 2 × Length of BC.</em>
Perimeter = 2 × 20.5 + 2 × 17
= 41 + 34
= 75 units.
<h3>Therefore, the perimeter of parallelogram ABCD is 75 units.</h3>
