Answer:

12

Step-by-step explanation:

p = -4

3p² - 18(-2 - p)

plug in p

3(-4)² - 18(-2 - (-4))

solve the exponent

3(16) - 18(-2 - (-4))

solve within the parentheses

3(16) - 18(-2 + 4)

3(16) - 18(2)

multiply each expression

48 - 36

subtract

The perimeter of a rectangle is 46 m if the with were doubled and on length were increased by 5 their perimeter would be 66 what
Kamila [148]

Answer:

18 and 5

Step-by-step explanation:

if 'x' - is the length and 'y' - the width of the rectangle, then

2(x+y)=46 - perimeter of the original rectangle and 2(2x+(y+5))=66 - the perimeter of the new rectangle.

\left \{ {{x+y=23} \atop {2x+y=28}} \right. \=> \ \left \{ {{x=5} \atop {y=18}} \right.

Finally, the length is x=5 and the width is y=18.

How many triangles can be constructed with sides measuring 1 m, 2 m, and 2 m?
Margaret [11]
Answer: B
Explanation: ONE triangle can be formed.
According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.
Here, the sides are 1 m, 2 m, and 2m. 1m + 2m = 3m > 2m (theorem followed) 2m + 2m = 4m > 1m (theorem followed)
Since, the triangle inequality theorem is followed, Hence, ONE triangle can be formed.
