Super easy so what your going to do is replace x with 5 and y with 3 (it says in the directions) for example number 1 3x-2y+4 so replace the variables with numbers so when there is a number next to a letter that means to multiply so 3x5-2x3+4 then you just solve and remember pemdas and when there bit two variables next to each other multiply hope this helps

Sardis was drawing a triangle. The first segment he drew was 10 centimeters. The 2nd side he drew was 12 centimeters. How long w

HACTEHA [7]

Answer:

see the explanation

Step-by-step explanation:

we know that

The<u><em> Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Applying the triangle inequality theorem

Let

c ----> the measure of the length of the third side

1) $10+12 > c$

$22 > c\\c < 22 cm$

2) $c+10>12$

$c > 12-10\\c >2 cm$

so

The solution for the length of the third side is the interval (2,22)

All real numbers greater than 2 centimeters and less than 22 centimeters

Find the perimeter and area of the composite shape...

tatiyna

Answer:

P = 30

A = 22

Step-by-step explanation:

Find perimeter first

P = 5 + 5 + 2 + 2 + 2 + 2 + 2 + 2 + 4 + 4

P = 10 + 12 + 8

P = 30

Now area

A = 2(5 * 2) + (2 * 1)

A = 2(10) + (2)

A = 20 + 2

A = 22
