Answer:
r = 6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
PR² = PQ² + QR² , substitute values
(r + 4)² = r² + 8²
r² + 8r + 16 = r² + 64 ( subtract r² from both sides )
8r + 16 = 64 ( subtract 16 from both sides )
8r = 48 ( divide both sides by 8 )
r = 6

<u>x </u><u>23.74</u>
940 ====== 23.50 multiply to 4
16450 ====== 23.50 multiply to 7
70500 ====== 23.50 multiply to 3
<u>+ 470000 </u> ====== 23.50 multiply to 2
557.890 ====== Add all the numbers together, move the decimal sign down to align with the result
<u />
Step-by-step explanation:
multipy the two sides by 2
n+4= -16
move the constant to the right change its sign
n= -16 - 4
calculate the difference
N= - 20
