The answer would be A.  The fact that the gradient of the new line is higher (12 versus 4) is evidence that the graph is steeper.<span />

Find the perimeter. Simplify your answer.<br> 4c+9<br> 70-5<br> 5c+2<br> 5c-3
pickupchik [31]

Answer:

Step-by-step explanation:

Perimeter = 4c + 9 + 7c - 5 + 5c + 2 + 5c - 3

                = 4c +7c + 5c +5c + 9 - 5 + 2  - 3

A triangle has sides which are consecutive odd integers and an
wolverine [178]

Answer:

Perimeter = 15

Step-by-step explanation:

We are told that the length of each of the 3 sides of the triangle are consecutive odd integers.

Thus means that we can write the 3 terms as;

(x - 2), x, (x + 2)

Thus, perimeter is;

P = (x - 2) + x + (x + 2)

P = 3x

If an angle is 120°, it means that the corresponding side that is directly opposite the angle is the largest side of the triangle.

Thus, this side is (x + 2)

Using cosine rule, we have;

(x + 2)² = x² + (x - 2)² - 2(x(x - 2))cos 120

Expanding, we have;

x² + 4x + 4 = x² + x² - 4x + 4 - (2x² + 4x)(-½)

This reduces to;

4x = x² - 4x + x² - 2x

2x² = 10x

2x = 10

x = 10/2

x = 5

Thus, other sides are;

(x - 2) = 5 - 2 = 3

And (x + 2) = 5 + 2 = 7

So,perimeter is;

P = 3x = 3 × 5 = 15
