So since xd is 5 that means ad is 10
now you have 2 sides all you need is to find the last side you can use Pythagorean theorem and get 26 for db
answer 26.
Answer:
8r⁶s³ - 5r⁵s⁴ + r⁴s⁵ + 5r³s⁶
Step-by-step explanation:
(8r⁶s³-9r⁵s⁴+3r⁴s⁵)-(2r⁴s⁵-5r³s⁶-4r⁵s⁴)
We need to combine like terms, take care the exponents of r and s
(8r⁶s³-9r⁵s⁴+3r⁴s⁵)-(2r⁴s⁵-5r³s⁶-4r⁵s⁴)
multiply the second parenthesis by -1
= 8r⁶s³-9r⁵s⁴+3r⁴s⁵-2r⁴s⁵+5r³s⁶+4r⁵s⁴
= 8r⁶s³ + (-9r⁵s⁴ + 4r⁵s⁴) + (3r⁴s⁵-2r⁴s⁵) + 5r³s⁶
= 8r⁶s³ - 5r⁵s⁴ + r⁴s⁵ + 5r³s⁶
Note: r⁶s³ is not like r³s⁶
6 because 12 in half is 6
Honestly I don’t even know
Answer:
Y = k/x for some fixed number constant k
7 = k/9
k = 63
so Y = 63/x
14 = 63/x
14 x = 63
x = 63/14 = 9/2
Step-by-step explanation:
not too hard ;)
