Answer:
-7x^2-3x
Step-by-step explanation:
-x * 7x + (-x) * 3
-7xx-3x
-7x^2-3x
Angles x and 64 deg are "complementary," so x+64=90, and x= 26 deg.

Look at the picture for the process.
Answer:
A = 16 13unit^2 + 9unit^2 = 5 √10 = 15.8 = 16
Step-by-step explanation:
For Pythagoras we square route
= x^2 = 13^13 + (one of the closer squares for x elimination)
x= 169 + 81 169 + 100 169 + 49 169+64 169 + 121
x = 250 or 269 or 218 or 233 or 290
x= 5√10 or 15.8 or √269 269 or √218 2.8 or √233 or 2.33 ( or √290 = ( √48+2) or 2.9
