Answer:

13

Step-by-step explanation:

there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.

hope this helps :))

Find the gradient and the intercept shown by the straight line 2x + 3y = 6

sveta [45]

Answer:

$\sf gradient =\dfrac{-2}{3}\\\\ y -intercept = 2$

Step-by-step explanation:

<h2>Equation of the line in slope intercept form:</h2>

$\sf \boxed{\bf y = mx +b}$

Here m is the slope or gradient and b is the y-intercept.

Write the given equation in slope-intercept form.

2x + 3y = 6

3y = -2x + 6

$\sf y =\dfrac{-2}{3}x +\dfrac{6}{3}\\\\ y = \dfrac{-2}{3}x + 2$

$\sf gradient =\dfrac{-2}{3}\\\\ y -intercept = 2$

The volume of a solid right pyramid with a square base is v units3 and the length of the base edge is y units. Write the express

Wewaii [24]

Answer:

h = V/y^2

Step-by-step explanation:

The volume of a right pyramid is given by the expression = Area of base × height.

Area of base = Area of square at the base

= y × y = y^2.

Now, we substitute these values:

V = y^2 × height

height = V/y^2
