<u>Answer </u><u>with</u><u> step by step explanation</u>

(1)(3 {x}^{2}  + 2xy + 7) - (6 {x}^{2}  - 4xy + 3) \\ 3 {x}^{2}  + 2xy + 7 - 6 {x}^{2}  + 4xy - 3 \\  =  - 3 {x}^{2}  + 6xy + 4

(2)9 {x}^{2}  - 2x + 3 - (4 {x}^{2}  + 7x - 5) \\ 9 {x}^{2}  - 2x + 3 - 4 {x}^{2}  - 7x + 5 \\  = 5 {x}^{2}  - 9x + 8

(3) {x}^{2}  - 5x + 6 \\  {x}^{2}  - 3x - 2x + 6 \\ x(x - 3) - 2(x - 3) \\ (x - 2)(x - 3)

Simplify. 5√ 10 <br> 1) 2√ 2) 2√2 3) 10√2 4) 5√
Nataly_w [17]

For this case we have that the expression in its exact form is the same, that is:

5 \sqrt {10}

If it is expressed in decimal form we have:

5 \sqrt {10} = 1.5849

If we want equivalent expressions, we must first mention the following property of powers and roots:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

Then, we can rewrite the expression as:

5 \sqrt {10} = \sqrt {5 ^ 2 * 10} = \sqrt {25 * 10} = \sqrt {250}

Answer:

5 \sqrt {10} = \sqrt {250} = 1.5849

Will give brainliest! Please explain how I solve the ratio 16/32=12/24
goldenfox [79]

To solve, simply simplify each fraction

(16/32)/(16/16) = 1/2

(12/24)/(12/12) = 1/2

True, the equation given to us is true.

hope this helps
