4(60q-190u-13b+17i) you have to factor the polynomials
I hope this helps you
180- 75 3/5
180-378/5
5.180-378/5
900-378/5
522/5

Answer:
-(-9) is 9
Step-by-step explanation:
-(-9)
(when there are two negatives multiplyed with eachother, the product will be postive)
+ 9
+ 9 = 9
Step-by-step explanation:
#7
the composite function from K to F :
(F o C) (x) = 9/5 (x - 273.15) + 32 (option D)
I am not quite sure what the question asks for,
But this is what i assume it wants:
Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A

: It looks like this in the calculator

× cos A=

(0.6489)
(

and cos cancels out)
A=

(0.6489)
A=49.54°
check:
cos 49.54=0.6489 (its right!)
