Answer:

Step-by-step explanation:

(a+b)^2=a^(2)+2ab+b^(2)

(a-b)^2=a^(2)-2ab+b^(2)

13)

(x+2)^(2)-(x-1)^2

x^(2)+4x+4-(x^(2)-2x+1)

x^(2)+4x+4-x^(2)+2x-1

6x+3

15)

(x+5)^(2)-(x+1)^2

x^(2)+10x+25-(x^(2)+2x+1)

x^(2)+10x+25-x^(2)-2x-1

8x+24

Nate weighs 6 pounds more than William. William weighs 3 pounds more than Todd.

djyliett [7]

Answer:

William weighs 111 pounds.

Step-by-step explanation:

N = x+6

W = x

T = x-3

x+6+x+x-3=336

3x + 3 = 336

3x = 336 - 3

x = 333/3

x = 111

The number of charter schools is 4 less than twice the number of alternative schools and there are 48 charter schools how many a

jarptica [38.1K]

Let x = the number of alternative schools.

Therefore, 2x - 4 = 48.
2x -4 +4 = 48 + 4
2x = 52
x = 26

Therefore, there are 26 alternative schools(You could check this answer by substituting x=26 into the equation above.).

Given:m<6=m<8b l l cprove:a l l b

makvit [3.9K]

1) From the data, we can see that

$\angle6=\angle8$

is given.

2) Next,

$\angle6=\angle7$

since they are alternate angles.

3) By substitution, these means that

$\angle7=\angle8$

4) Finally, a || b since

$\angle7=\angle8$

this is because, angle 7 and angle 8 are corresponding angles.

Corresponding angles are angles that are on the same corner at each intersection. For instance, 2 and 6

4 and 8, 1 and 5, 3 and 7

In our case, 7 and 8 are corresponding angles
