avanturin [10]

Answer:

$11\sqrt{2} - 5\sqrt{7}$

Option (A) is the correct answer.

Step-by-step explanation:

$9\sqrt{2} - 3\sqrt{7} + \sqrt{8} - \sqrt{28}$

Now, $\sqrt{8} = \sqrt{2 \times 2 \times 2} = 2\sqrt{2}$

$\sqrt{28} = \sqrt{2 \times 2 \times 7} = 2\sqrt{7}$

∴ $9\sqrt{2} - 3\sqrt{7} + \sqrt{8} - \sqrt{28}$

= $9\sqrt{2} - 3\sqrt{7} + 2\sqrt{2} - 2\sqrt{7}$

= $9\sqrt{2} + 2\sqrt{2} - 3\sqrt{7} - 2\sqrt{7}$

= $11\sqrt{2} - 5\sqrt{7}$

Therefore option (a) is the correct answer.

Hellp with theseeee pls !! Asappp

Llana [10]

Answer:

a is 60 ft^3 and b is 45

Step-by-step explanation:

b is 45 because 60/4 is 15, which would mean that 4/4 is 60, and since it says 3/4, you subtract 15 from 60 to get 45.

a is 60 because volume equals length times width times height, the three measurements shown

(edit)

and when multiplied you get 60 altogether.

Mac has 117 white and black

olga55 [171]

Answer:

The number of white horses is 52

Step-by-step explanation:

Let

x ----> the number of black horses

y ----> the number of white horses

we know that

$x+y=117$ ----> equation A

$\frac{x}{y}=\frac{5}{4}$

$x=\frac{5}{4}y$ ----> equation B

Substitute equation B in equation A and solve for y

$\frac{5}{4}y+y=117$

$\frac{9}{4}y=117$

$y=117(4)/9\\y=52$

therefore

The number of white horses is 52
