4. Evaluate the expression:
[tex]\[3 \times (6+5) + (8+4) \times 2 - 50\][/tex]

Sagot :

Certainly! Let's solve the expression step-by-step to make sure everything is clear. Here is the given expression:

[tex]\[ [3 \times (6 + 5) + (8 + 4) \times 2] - 50 \][/tex]

1. Calculate the sums inside the parentheses:

[tex]\[ 6 + 5 = 11 \][/tex]
[tex]\[ 8 + 4 = 12 \][/tex]

2. Substitute these values back into the expression:

[tex]\[ [3 \times 11 + 12 \times 2] - 50 \][/tex]

3. Perform the multiplications:

[tex]\[ 3 \times 11 = 33 \][/tex]
[tex]\[ 12 \times 2 = 24 \][/tex]

4. Add the results of the multiplications:

[tex]\[ 33 + 24 = 57 \][/tex]

5. Subtract 50 from the result of the addition:

[tex]\[ 57 - 50 = 7 \][/tex]

Therefore, the value of the expression [tex]\([3 \times (6 + 5) + (8 + 4) \times 2] - 50\)[/tex] is [tex]\( 7 \)[/tex].
