Answer:
<u>∠AEB = 72°</u>
Step-by-step explanation:
<u>Finding x</u>
- ∠AEB = ∠DEC (Vertically opposite angles)
- 7x - 5 = 2(4x - 8)
- 7x - 5 = 8x - 16
- 8x - 7x = -5 + 16
- x = 11
<u>Finding ∠AEB</u>
- 7x - 5
- 7(11) - 5
- 77 - 5
- <u>∠AEB = 72°</u>
Answer:
A) The expression is a trinomial.
Step-by-step explanation:
If the degree is 2, the expression would be a binomial, not a trinomial. If this answer is correct, please make me Brainliest!
L=16
W=21
Set up a systems of equations:
x=length
y=width
xy=336
x+5=y
Use substitution to solve:
x(x+5)=336
x^2+5x=336
Solve using factoring:
x^2+5x-336=0
(x-16)(x+21)=0
x=16 and x= -21
Since length can't be negative, l=16
To find width, plug length into the first equation:
(16)y=336
y=21
So...
L=16

Step-by-step explanation:
Given,
Yearly movie rental cost = $231
Registration fee = $15
1 year = 12 months
Let,
x be the fee per month.
12x+15=231
Dividing both sides by 12
New members pay a fee of $18 per month.
