Answer:

The answer is option 1.

Step-by-step explanation:

Firstly, you have to elaborate the expression :

{x}^{2}  + 10x + 21

=  {x}^{2}  + 3x + 7x + 21

Next you have to take out the common factors and factorize it :

{x}^{2}  + 3x + 7x + 21

= x(x + 3)  +  7(x + 3)

= (x + 7)(x + 3)

Write the equation of the line that passes through the points (0,8) and (-1, –4).
andrey2020 [161]

Answer:

Step-by-step explanation

First, let's remember the equation for point-slope form and how to find the 'm' value:

y-y1 = m (x-x1)\\m = rise/run\\m = \frac{-4-(8)}{-1-(0)} = 12

Now plug your m value and (x1, y1) into point-slope form:

y - 8 = 12(x-0)\\reduce\\y=12x+8

PLEASE HELP!! I WILL MARK THE FIRST CORRECT ANSWER BRAINLIEST!!))What is the volume of this cylinder?
Aleksandr-060686 [28]

Answer:

V = 6079.04 ft³

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

Here diameter = 22 , then r = 22 ÷ 2 = 11 and h = 16 , then

V = 3.14 × 11² × 16

   = 3.14 × 121 × 16

  ≈ 6079.04 ft³ ( to the nearest hundredth )

Determine the unknown side lengths’ to the nearest tenth. for the first question and also please help with question 6
Levart [38]

Answer:

z =15cm and

y=9.0cm

Step-by-step explanation:

Use sine rule

12/ sin53 = z / sin 90

Z = 12 x sin 90 / sin 53

Z = 15cm

To find y the angle opposite to y will be 180-(90+53)=37º

So

15/sin 90= y/sin37

y= 15 x sin37 /sin 90

y = 9.0cm
