-657
Step-by-step explanation:

Substituting the value of a and b

The value of 3a²-4ab-26² is -657
Answer:
50
Step-by-step explanation:
4 x 10 = 40 and 2 x 5 = 10 so add them together
(-2+8i)x(3-10i)
-2 x 3 - 2 x (-10i) +8i x 3- 8i x 10i
-6+20i+24i - 80i ^2
-6+20i+24i - 80 x (-1)
-6+20i+24i + 80
Answer: 74+44i
Answer:
3 11/20 miles
Step-by-step explanation:
Monday = seven -quarters of a mile
= 7/4 miles
Tuesday = nine-fifths of a mile
= 9/5 miles
How many miles did she ride altogether?
Total miles she rode altogether = Monday + Tuesday
= 7/4 + 9/5
= (35+36)/20
= 71/20
= 3 11/20
Total miles she rode altogether = 3 11/20 miles
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
In this problem we have double parentheses. Which one should we solve first? The answer to that is always the inner most ones:
13[ 6² ÷ (5² - 4²) + 9]
5² - 4²
^^^Here you will have to first take the square of both values
25 - 16
9
13[ 6² ÷ (9) + 9]
Now for the exponents
13[ 6² ÷ (9) + 9]
6²
36
13[ 36 ÷ 9 + 9]
Now for the division:
13[ 36 ÷ 9 + 9]
36 ÷ 9
4
13[ 4 + 9]
Now for the addition
13[ 4 + 9]
4 + 9
13
13[13]
Now for multiplication
169
