Answer:
-9.5116
Step-by-step explanation:
-1.58 * 6.02.
The easy way is to use your calculator.
To do it manually you can multiply -158 by 2, then by 10 and then by 600.
Add these 3 results.
This gives -95116.
Now you have 4 numbers after the decimal point in -1.58 and 6.02 so counting from the right in -95116 we locate the decimal point:
= -9.5116.
Expanding 8x^3, we multiply 8*8 and x^3 by x^3 to get 64x^6. Since we know that the cube root of 64 is 4, we can separate that. Next, since you add exponents while multiplying, 6/3 is the exponent for the cube root of x^6=x^2. Therefore, your answer is 4x^2
Answer:2d+3
2(8)+3
Multiply 2 and 8
16+3
19
So the answer is 19

Answer:
(3, 2), (2, 3)
Step-by-step explanation:
x + y = 5
xy = 6
Solve the first equation for x.
x = 5 - y
Substitute 5 - y for x in the second equation.
xy = 6
(5 - y)y = 6
5y - y² = 6
y² - 5y + 6 = 0
Factor.
(y - 2)(y - 3) = 0
y - 2 = 0 or y - 3 = 0
y = 2 or y = 3
Now substitute 2 for y in the first equation and solve for x.
x + y = 5
x + 2 = 5
x = 3
One solution is x = 3; y = 2, or (3, 2).
Now substitute 3 for y in the first equation and solve for x.
x + y = 5
x + 3 = 5
x = 2
Another solution is x = 2; y = 3, or (3, 2).
Answer: (3, 2), (2, 3)
