Solve for a: a²-8a +12 is A. -2,-6 B. 2,6 C.-3,-4 D. 3,4

1 answer:

7 0

If you would like to solve the equation a^2 - 8*a + 12 = 0 for a, you can calculate this using the following steps:

a^2 - 8*a + 12 = 0
(a - 6) * (a - 2) = 0
1. a = 6
2. a = 2

The correct result would be B; 2, 6.

What is the value of tan (B) in the diagram?

hodyreva [135]

Answer:

The correct answer is third option

1/√3

Step-by-step explanation:

From the figure we can see a right angled triangle ABC.

Right angled at C.

AB = 10

AC = 5

BC = 5√3

Points to remember

Tan θ = Opposite side/Adjacent side

To find the value of tan(B)

Tan B = Opposite side/Adjacent side

= AC/BC

= 5/5√3

= 1/√3

Therefore the value of tan(B) = 1/√3

Leslie has a voucher worth $5 coupon from Wal-Mart.She visits the store and purchases a wallet that amounted to double the price

jasenka [17]

Answer:

The Cost of wallet was $26.30.

Step-by-step explanation:

Given:

Total billed after redeeming voucher = $34.45

Voucher worth = $5

We need to find the cost of Wallet.

Solution:

Let the amount paid for groceries be 'x'.

Now Given:

She purchases a wallet that amounted to double the price she paid for the groceries she bought.

Cost of wallet = $2x$

Now to find the cost of wallet we will consider the amount before redeeming the voucher.

Hence Total bill before redeeming the voucher = $\$34.45+\$5=\$39.45$

Now We can say that;

Total bill is equal to sum of Cost of wallet and Cost of groceries.

framing in equation form we get;

$x+2x=39.45\\\\3x=39.45$

Dividing both side by 3 we get;

$\frac{3x}{3}=\frac{39.45}{3}\\\\x=\$13.15$

Cost paid for groceries = $13.15

Cost paid for wallet = $2x=2\times 13.15 =\$26.30$

Hence the Cost of wallet was $26.30.
