Answer:

3. 50

4. 1

Step-by-step explanation:

3.

-5a + 2b - 6c

Substitute the variables, knowing that:

a = -6, b = 4, and c = -2

-5(-6) + 2(4) - 6(-2)

Multiply -5 and -6.

30 + 2(4) - 6(-2)

Multiply 2 and 4.

30 + 8 - 6(-2)

Multiply -6 and -2.

30 + 8 + 12

Add 30 and 8.

38 + 12

Add 38 and 12.

50

4.

√(5x) + 2y

Substitute the variables, knowing that:

x = 5 and y = -2

√(5(5)) + 2(-2)

Multiply 5 and 5.

√(25) + 2(-2)

Multiply 2 and -2.

√(25) - 4

Take the square root of 25.

5 - 4

Subtract 4 from 5.

Answer:

ok when you first loaded the x y z fraction question on another page you asked for help where two people had answered saying it was 3 they were wrong the answer is 6 as 18/3 = 6   the answers below are for this question above hope this helps you also    

Step-by-step explanation:   QU 1  = 50   + QU 2 = 1

Qu 1)   -5 a + 2b - 6c   = rewrite out empty brackets for a  and b and c   Then step 2 is to input number's in brackets as a = -6  b = 4 and c = -2 we substitute  so write out first  (-5 ( )) + 2(  ) - (6(  )) if all polynomials are + - we show so like in bold then its easier to determine what to fill in to substitute   (-5 (-6)) + 2(4) - (6(-2))  =  30 + 8 + 12 = 50 if we rewrote like this instead  (-5 (-6)) + 2(4) -6(-2)) it would also be right   so the answer is 50    Qu 2)  sq rt 5x +2 y =  (when x = 5 and y = -2) sq rt 5(5) and + 2(-2)  = sq rt 25 -4  =  5 -4 = 1   Hope this helps also free worksheet info for graphs to explain things math.utah.edu/~wortman/1050-text-calp.pdf  just type www in front helps all students that are struggling with graphs

Answer:Yes that is correct, 3(2t + d) is equal to 6t+3d. This is due to the distributive property of multiplication, or as I like to call it, the DPM. The DPM works for all multiplication and praentheses problems. For example, 7(2t+3d)=14t+21d. You multiply the coefficient of the whole parentheses by each number/variable in the equation. Another example is 5(n+s)=5n+5s.
