Mathematics

Mazyrski [523]3 years ago
5 0

Answer:

Perimeter = 6x² + 8x

Step-by-step explanation:

Perimeter = 2(length + width)

perimeter = 2((x²+x)+(2x²+3x))

perimeter = 2(x²+2x² + x+3x)

perimeter = 2(3x² + 4x)

perimeter = 2*3x² + 2*4x

perimeter = 6x² + 8x

someone please help, write in point-slope form an equation of the line that passes through the point (8, 9) with slope 7.
Bess [88]

Answer:

y=7x-47

Step-by-step explanation:

(8, 9) = (x_1,y_1) \\ m = 7 \\ y  - y_1 = m(x - x _1) \\ y - 9 = 7(x - 8)

y - 9 = 7x - 56 \\ y = 7x - 56 + 9 \\ y = 7x - 47

Max is scuba diving at elevation of -64.5 feet, when friend signals to come higher. Max makes 2 ascents, each an equal distance
KengaRu [80]

Answer: - 42.95 feet

Explanation:

Let each ascent be x. Thus,

2 equal ascents = 2x

From the information given,

initial position = - 64.5 feet

Final position after 2 ascents = - 21.4 feet

This means that

- 64.5 + 2x = - 21.4

2x = - 21.4 + 64.5

2x = 43.1

x = 43.1/2

x = 21.55

Thus, Max's elevation after the first ascent is

- 64.5 + 21.55

= - 42.95 feet
