What is the value of the expression
(25 - 7) x 2 + 4 + 2?

42.

Step-by-step explanation:

First, you identify what method you need to use for solving this problem. I used Pemdas. Pemdas is the steps to take for most equations. Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction.

You do the parenthesis part of the equation first. 25-7= 18.

Next, following the order of Pemdas, you multiply the answer you just got from the parenthesis by 2. 18x2= 36.

Then, you add 4 to the answer to the last step. 36+4= 40.

Lastly, you add 2 to the answer from the last step. 40+2= 42.

I hope this benefits you. Good luck!

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
