If g = 3, evaluate (solve) the following expression. 2g + 7=

13.

Step-by-step explanation:

2g + 7

= 2(3) + 7

= 6 + 7

= 13.

13

Step-by-step explanation: In this problem, we have the xpression 2g + 7 and we want to evaluate the expression when g is equal to 3.

To evaluate an expression, we simply plug the value of the variable into the expression and solve. So here, since g is equal to 3, we have 2 (3) + 7. 2 × 3 is equal to 6 so we have 6 + 7 which is equal to 13.

So the value of our expression when g is equal to 3 is 13.

Remember, when we see a variable like g next to a number, it means multiplication so you want to multiply by the value of the variable.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
