Answer:   -202

Step-by-step explanation:

Lets split this expression in neighbouring pares and calculate the value of each pair .

1-3=-2

2-4=-2

3-5=-2

4-6=-2

**************

101-103=-2

As we can notice the value of each pair is -2

The number of such pairs is 101.

So to get the total amount we have (-2)*101=-202

LMN≅PQR
tresset_1 [31]
<span>LMN≅PQR means that point L is equal to P, point M is equal to Q, and point N is equal to R. All lines are the same.

Point Q has an angle of 72, which means that point M also has an angle of 72.

Now you have two angles to find x. All interior angles of a triangle add up to 180, so you can set up the following equation to find x:

72 + 36 + x = 180

Subtract 36 from both sides.

72 + x = 144

Subtract 72 from both sides.

x = 72

The angle of point L, x, is 72.

For all values of x, which expression is equivalent to 4(5x + 3) - 4x?
kaheart [24]
4(5x + 3) - 4x
4*5x = 20x
4 * 3 = 12
20x and 4x are like terms,so 20x - 4x=16x
12 doesn’t have anything to go with,so it just stays

16x + 12 (B is the correct answer)
