Answer:
a = 0
Step-by-step explanation:
3(a + 4) - 5(a - 2) = 22
3a + 12 - 5a + 10 = 22
-2a + 22 = 22
-2a = 0
a = 0
First you distribute
17(a) - 17(15) = 153
then solve what you can
17(a) - 255 = 153
then add to cancel out the subtraction
17(a) - 225 = 153
+225 +225
17(a) = 378
then divide
17(a) = 378
/17 /17
a= 22.2352941
a= 22.2
Answer:
b=23 degrees
Step-by-step explanation:
a was 66 degrees so b=23 degrees 180-90-66=23
a=1
b=3
a^3*b^2-2a=1^3 * 3^2 -2*1 = 1*9 -2 = 9-2= 7
