Tell whether the triangle with the given side lengths is a right triangle

Andreas93 [3]

Answer:

not a right triangle

Step-by-step explanation:

The Pythagorean Theorem states that If a triangle is a right triangle,

the hypotenuse^2 will equal to shorter^2 + longer^2

hypotenuse = 18, shorter side = 4, longer side = 17

18^2 = 4^2 + 17^2

324 = 16 + 289

324 = 305

That is false, therefore the triangle is not a right triangle

Elis [28]

Answer:

Sum of their present ages = 20 years

Step-by-step explanation:

Present age :

Neha's age = x years

Reemas' age = x - 4

After 5 years:

Neha's age = (x +5) years

Reemas' age = (x - 4 + 5 ) = x + 1

Sum of the ages of Reema and Neha will be 30

Therefore,

x + 5 + x + 1 = 30

x + x + 5 + 1 = 30

2x + 6 = 30

2x = 30 - 6

2x = 24

x = 24/2

x = 12

Neha's age = 12 years

Reema's age = 12 - 4 = 8 years

Sum of their present ages = 12 + 8 = 20 years

Complete the data table for the function f(x) = -x - 2 + 2.

alexgriva [62]

Given the following function:

$\text{ f(x) = }\sqrt[]{-x\text{ -2}}\text{ + 2}$

y = f(x)

Therefore, let's complete the data table by substituting each x-values to be able to get the respective y-values,

We get,

At x = -2,

$\text{ y = f(x) = }\sqrt[]{-x-2}\text{ + 2}$ $\text{f(-2) = }\sqrt[]{-(-2)-2}\text{ + 2}$ $\text{ = }\sqrt[]{2\text{ - 2}}\text{ + 2}$ $\text{ = }\sqrt[]{0}\text{ + 2}$ $\text{ y = f(-2) = 2}$

Therefore, y = 2 at x = -2.

At x = -3,

$\text{ y = f(x) = }\sqrt[]{-x-2}\text{ + 2}$ $\text{f(-3) = }\sqrt[]{-(-3)-2}\text{ + 2}$ $\text{= }\sqrt[]{3-2}\text{ + 2}$ $\text{= }\sqrt[]{1}\text{ + 2}$ $\text{= }1\text{ + 2}$ $\text{ f(-3) = 3}$

Therefore, y = 3 at x = -3.

At x = -6,
