Answer:
x = 2
Step-by-step explanation:
For secants that intersect at an external point, the product of the external length and total length is a constant.
... 3·(3 +5) = 4·(4 +x) . . . . . write the two products, and set them equal
... 24 = 16 +4x . . . . . . . . . . eliminate parentheses
... 8 = 4x . . . . . . . . . . . . . . .subtract 16
... 2 = x . . . . . . . . . . . . . . . . divide by 4
Answer:

Step-by-step explanation:

Answer:
The values of given expressions are:
1. gh = -21
2. g^2 - h = 46
3. g + h^2 = 2
4. g + h = -4
5. h - g = 10
6. g - h = -10
Step-by-step explanation:
Given values of g and h are:
g = -7
h = 3
<u>1. gh</u>
The two numbers are being multiplied
Putting the values

<u>2. g^2-h</u>
Putting the values

<u>3. g+h^2</u>
Putting the values

<u>4. g+h</u>
Putting the values

<u>5. h-g</u>
Putting the values

<u>6. g-h</u>
Putting values

Hence,
The values of given expressions are:
1. gh = -21
2. g^2 - h = 46
3. g + h^2 = 2
4. g + h = -4
5. h - g = 10
6. g - h = -10
y = −2x + 1
4x + 2y = −1
Replace Y in the second equation with the value of Y in the first one.
4x + 2(-2x +1) = -1
Distributive Property:
4x + -4x + 2 = -1
Combine like terms:
2 = -1 which is not true, so there are no solutions.
