Answer:
x=-1±4√31/3 ft is the height
Step-by-step explanation:
let the height be x ft.
then the length would be 3x+2
area = L*H= x(3x+2)
165=3x²+2x
0= 3x²+2x -165
dividing the whole equation by 3
0=x²+2x/3-55
(x)²+2(x)(1/3) +(1/3)² -55 -(1/9)=0
(x+1/3)²- 495-1/9=0
(x+1/3)²= 496/9
taking square root on both sides
(x+1/3)= ±4√31/3
x= ±4√31/3-1/3
x=-1±4√31/3 ft is the height
Anna's balance after writing check #1620 was B) $1606.42
Step-by-step explanation:
Step 1; Whenever you make a payment, make a cash withdrawal the money in your account decreases as you're giving your money to someone else. So the money spent or taken is reduced from the balance in your account.
Whenever you get your paycheck or make a deposit the money you have in your account increases. So the amount of money put in or the money you are paid is added with the balance you have in your account.
Step 2; Anna had a balance of $2,339.27 before writing the check #1620. She withdraws an amount of $732.85 under the description of the city bank. As she withdrew money, withdrawn money is subtracted from the balance.
Balance after writing the #1620 check = Balance before writing the #1620 check - amount of money withdrawn = $2,339.27 - $732.85 = $1,606.42,
So her balance after writing check #1620 was $1,606.42.
Answer:
Step-by-step explanation:
According the Triangle sum theorem:
m<T + m<U + m<V =180
x + 2x + x + 80 = 180
solve: x=25
Therefore m<T = 25, m<U = 50, and m<V = 105
