2(a + 6) → 2(2 + 6) = 2(8) = 16
A. 2a + a² → 2(2) + 2² = 4 + 4 = 8
B. 4a + 8 → 4(2) + 8 = 8 + 8 = 16
C. 2a + 12 → 2(2) + 12 = 4 + 12 = 16
D. a⁴ + 2 = 2⁴ + 2 = 16 + 2 = 18
18 > 16
Answer:
D
Step-by-step explanation:
the value of the given expression when a = 2 is
2(2 + 6) = 2 × 8 = 16
calculating the values of the expressions when a = 2
A (2 × 2 ) + 2² = 4 + 4 = 8 ← less than 16
B (4 × 2) + 8 = 8 + 8 = 16 ← not greater than 16
C (2 × 2) + 12 = 4 + 12 = 16 ← not greater than 16
D + 2 = 16 + 2 = 18 ← greater than 16
It is about 0.83 in decimal or 10 twelfths (10/12) in fraction form. I hope this helped! So sorry if it's wrong!!!
y=3x+6
Step-by-step explanation: 3=3(-1)+b
3=-3+b
+3 +3
6=b
AC² = 10.8²+14.4² = 324
AC = √324= 18
area = AC.DC÷2
area=18×24÷2
area=216
