Question

evaluate each using the values given.

1. ( y + y + y + x ); use ( x = 10 ), and ( y = 9 )
2. ( mp - (m + p) ); use ( m = 6 ), and ( p = 8 )
3. ( n^2 + 9 - m ); use ( m = 8 ), and ( n = 5 )
4. ( x + 4(x - y)^3 ); use ( x = 1 ), and ( y = 1 )
5. ( a - (b + 1 + 2) + b ); use ( a = 7 ), and ( b = 4 )
6. ( yx - (y + 2 + x) ); use ( x = 7 ), and ( y = 5 )

Explanation:

Step1: Substitute x=10, y=9

$9 + 9 + 9 + 10$

Step2: Calculate the sum

$27 + 10 = 37$

Step1: Substitute m=6, p=8

$6 \times 8 - (6 + 8)$

Step2: Compute multiplication and sum

$48 - 14$

Step3: Calculate the difference

$48 - 14 = 34$

Step1: Substitute m=8, n=5

$5^2 + 9 - 8$

Step2: Compute square and simplify

$25 + 9 - 8$

Step3: Calculate the result

$34 - 8 = 26$

Step1: Substitute x=1, y=1

$1 + 4(1 - 1)^3$

Step2: Compute inside the parentheses

$1 + 4(0)^3$

Step3: Calculate the final value

$1 + 0 = 1$

Step1: Substitute a=7, b=4

$7 - (4 + 1 + 2) + 4$

Step2: Compute inside the parentheses

$7 - 7 + 4$

Step3: Calculate the result

$0 + 4 = 4$

Step1: Substitute x=7, y=5

$5 \times 7 - (5 + 2 + 7)$

Step2: Compute multiplication and sum

$35 - 14$

Step3: Calculate the difference

$35 - 14 = 21$

Answer:

1. 37
2. 34
3. 26
4. 1
5. 4
6. 21
