Answer:

look below

Step-by-step explanation:

i dont know what that +... thing is

but when youre adding the negatives youre really just adding that number so this is just

48+45+42+81+84

45+42 is 87

now we have

48 + 87 + 81 + 84

87 + 81 is 168

48 + 84 is 132

now we have

168 + 132 and that is exactly 300

again dont know what the ... is so cant help you there

Answer:

2√14m

Step-by-step explanation:

Hypothenus = 9m

Second side = x

third side = 5m

Using Pythagoras theorem

9² = x² + 5²

81 = x² + 25

x² = 81 - 25

x² = 56

x = √56

= √4 × √ 14

= 2√14m

1. What is the slope of a line that is parallel to the line represented by the equation 3x + 4y = 12?
inn [45]

Answer:

Explained Below

Step-by-step explanation:

first we need to turn the equation into point slope form.

3x + 4y = 12

4y = -3x + 12

y = -0.75 + 3

Parallel lines don't have a change in slope because they run parallel. Your answer would be -0.75 or -3/4.
