Answer:
B 7
Step-by-step explanation:
Since the triangles are similar by AAA
We can use ratios to find the length x (which is PR)
5 15
-------- = ------------
x 21
Using cross products
5 * 21 = 15 *x
Divide each side by 15
5/15 * 21 = 15x/15
1/3 * 21 =x
7 =x
Answer:
$80.73
Step-by-step explanation:
115 * 0.35 = $40.25 off
115 - 40.25 = $74.75 after sale
add tax (0.08)
74.75 * 0.08 = $5.98 tax
74.75 + 5.98 = $80.73 in total
The correct answer is H=5
141.3/3.14/3²=5
U just have to move over the 3 to the right side and minus, and voilaa the answer is B. Have a great day!
<u>Answer</u>
8√2
<u>Explanation</u>
Simply: 4√2 + 7√2 - 3√2
Let √2 = x
4√2 + 7√2 - 3√2 = 4x + 7x - 3x
= 11x - 3x
= 8x
Substituting x with √2
4√2 + 7√2 - 3√2 = 8√2
