$3d^2=10-13d\\3d^2+13d-10 = 0\\(3d -2)(d+5) = 0$

This is the function factored

To find their solutions, we just need to set (3d - 2) = 0 and (d + 5) = 0

d= 2/3 , -5

Hope that helps!

Svetllana [295]

Answer: biggest no.=27. Smallest number=9

Step-by-step explanation:

Let's take the smallest number as x and the biggest number as 3x since it is 3 times bigger than x.

The sum of these two numbers is 36

3x+x=36

4x=36

X( smallest number)=36/4: 9

While, the biggest number is 3x: 3×9=27

Solve the given equation state the number and type of roots x^2-5x-36=0

just olya [345]

We can solve this quadratic equation using factorisation method as follows

:x2−5x−36=0

x2+4x−9x−36=0

x(x+4)−9(x+4)=0

(x+4)×(x−9)=0

x+4=0orx−9=0

x=−4orx=9

The radius of a circular baking tray is 6 cm. Find its area correct to 2 decimal places. Use the π button on your calculator for

ELEN [110]

Answer:

$A \approx 113.10cm^2$

Step-by-step explanation:

The circle is a flat surface or area limited or closed by a circumference. It is a two-dimensional figure and is formed by making a curve where it will always have the same distance to the center. Its area can be calculated using the following formula:

$A=\pi r^2\\\\Where:\\\\r=radius$

Therefore the area of the circular baking tray is:

$A=\pi (6)^2=\pi*36=36 \pi=113.0973355\approx 113.10 cm^2$
