Answer:
118 degrees
Step-by-step explanation:
All angles of any triangle have to add up to 180, so 25+37 equals 62. The next angle has to be 118 degrees, because 180-62 equals 118
Y(5y) + y(4) + 3y^2
5y^2 + 4y + 3y^2
8y^2 + 4y
If I understand your sequence, then this is the "closed form" of the sequence:
a_n = 63 - 4 n
Sum = (59, 55, 51, 47, 43, 39, 35, 31, 27, 23, 19, 15, 11, 7, 3) = 465
Answer:
2+2+2+2 or 2*4
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
4x−12=16
Step 1: Add 12 to both sides.
4x−12+12=16+12
4x=28
Step 2: Divide both sides by 4.
4x/4 = 28/4 = 7
x=7
