Which of the following is the simplified expression of 2 square root of -16 + the square root of 225 in standard form, a plus b

LuckyWell [14K]

Answer:

The standard form like $(a+bi)$ will be: $15+8i$

Step-by-step explanation:

Given expression is: $2\sqrt{-16}+\sqrt{225}$

First factoring out -16 as (-1×16) , we will get....

$2\sqrt{-1}*\sqrt{16}+\sqrt{225}$

Now, replacing $\sqrt{-1}$ as $i$ .......

$2i\sqrt{16}+\sqrt{225}$

Finally, simplifying the radicals in the above expression, we will get......

$2i*4+15\\ \\ =15+8i$

Thus, the standard form like $(a+bi)$ will be: $15+8i$

Pls help if you can Thx!

N76 [4]

GIVEN:

Cost of a taco and a cup of tea = $2.10

x + y = 2.10 ...(1)

Cost of 2 tacos and 3 cup of tea = $5.15

2x + 3y = 5.15 ...(2)

ANSWER:

On solving eq(1), we get

x = 2.10 – y

Substitute the value of x in eq(2), we get

2(2.10 – y) + 3y = 5.15
4.20 – 2y + 3y = 5.15
y = 5.15 – 4.20
y = 0.95

So, x = 2.10 – 0.95

x = 1.15

Hence, Cost of a taco is $1.15

So, Correct choice - [E] $1.15
