The legs of a right triangle are 4 units and 7 units. What is the length of the hypotenuse?A. square root 33 units
B. square root 65 units
C. 33 units
D. 65 units

Answers

Answer:

Correct option is:

B. square root 65 units

Step-by-step explanation:

Pythagorean theorem states that the square of hypotenuse is equal to the sum of squares of the legs of the right angled triangle.

Here, we are given that:

The legs of a right triangle are 4 units and 7 units.

By Pythagoras theorem

Hypotenuse²=4² +7²

= 16+49

= 65

⇒ Hypotenuse= $√(65)$

Hence, Correct option is:

B. square root 65 units

the square root of 65 units

Suppose y is a positive integer.If x-(-y)=z will z be greater than x ?

Answers

Integers are all numbers without decimal point.

z will always be greater than x

Given that:

$x - (-y)=z$

Open the bracket

$x + y=z$

Rewrite as:

$z =x + y$

From the question, we understand that y is positive.

This means that, irrespective of whether x is positive or negative; the value of z will always be greater than x.

Answers

4 (x - b) = x Use the DIstributive Property [(4(x) - 4(b)]
4 x - 4b = x Add 4b to both sides
4x = 4b + x Subtract x from both sides
3x = 4b Divide both sides by 3
x = $(4b)/(3)$
