b1=5

b2=3

h=4

(5+3)/2=4

4*4=16

1.The amount of space around an object.
Mekhanik [1.2K]

Answer:

  1. Mass
  2. Surface area
  3. Volume

Step-by-step explanation:

The size of a surface. The amount of space inside the boundary of a flat (2-dimensional) object such as a triangle or circle, or surface of a solid (3-dimensional) object

<u>Mass </u>

A property of a physical body and a measure of its resistance to acceleration when a net force is applied.

<u>Surface </u>

The area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

<u>Volume </u>

The Measure of the amount of space that a substance or an object takes up.

To find the box to the top left, we can multiple the sides like rectangles. To find the top left box, we can multiply -1 and 0.5y to get -0.5y.

To find the box on the bottom right, we can multiply the sides like rectangles again. To find the bottom right box, we can multiply 24x and 3 to get 72x.

Given the quadratic equation ax²-5b+4a=0, where a and b are constants has two real an equal roots,find a:b​
sergiy2304 [10]

Answer:

Therefore either a:b = 5:4 or a:b=-5:4

Step-by-step explanation:

ax²-5bx+4a=0

Since the quadratic equation has two real root.

Then b²-4ac>0

Here a= a , b= -5b and c=4a

∴(-5b)²-4.a.4a=0

⇔25b²=16a²

⇔5b=±4a

\Leftrightarrow \frac{a}{b} =\pm\frac{5}{4}

Therefore either a:b = 5:4 or a:b=-5:4

JK= 4x+3,<br> JL= 47, <br> KL= 9x+5<br> Find KL
Anuta_ua [19.1K]

Answer:

<h2>x = 3</h2><h2></h2>

Step-by-step explanation:

JK + KL = JL

(4x + 3) + (9x + 5) = 47

4x + 9x = 47 - 3 - 5

13x = 39

x = 39 / 13

x = 3
