BRAINLIEST ANSWER!! The product of 3, and a number increased by seven, is -36. Translate the equation, then solve.
EleoNora [17]

Product is multiplication.

Let the number = x


3 *( X+7) = -36

Use distributive property:

3x +21 = -36

Subtract 21 from each side:

3x = -57

Divide both sides by 3:

x = -57 /3

x = -19


Check: 3 * (-19 +7) = 3 * -12 = -36


The number is -19

an arc welder provides 250 amps of current when operating with a voltage of 40 volts. what is the power required by this welder
FinnZ [79.3K]
The power(P) of the circuits is the product of the voltage (V) in volts and current(I) in amperes. 
                                        P = IV

Substituting the known values to the equation,
                                     P = (250 amps) x (40 volts) = 10,000 Watts

Thus, the answer is 10,000 Watts.
