Answer:
1) 4
2) 15/2
3) 75
Step-by-step explanation:
Answer:
55 degrees
Step-by-step explanation:
<u>We are given:</u>
aᵇ = bᵃ
b = 2a
<u>Finding (a+b):</u>
<u>Finding a:</u>
replacing b by 2a in the first equation, we get:
(a²)ᵃ = (2a)ᵃ
(a²)ᵃ = 2ᵃ * aᵃ
a²ᵃ / aᵃ = 2ᵃ [dividing both sides by aᵃ]
aᵃ = 2ᵃ [because xᵃ / xᵇ = xᵃ⁻ᵇ]
a = 2 [raising both sides to 1/a]
<u>Finding b:</u>
We are given that b = 2a
now that we know what a equals, we will plug that value here
b = 2(2)
b = 4
<u>Finding a+b:</u>
We found that a = 2, b = 4
a + b = 2 + 4 = 6
Answer: 96 square inches
Step-by-step explanation:
A=1/2bh
A=1/2*16*12
A=8*12
A=96
