Answer:
18. 28 cm*2
19. 24 m
Step-by-step explanation:
18. length × l = 16
l*2= 16
l = 4
RQ = 4 cm
PR =7cm
Area of parallelogram = b×h
= 7×4
=28cm*2
19. 8 +8 + (6-2) +( 6- 2)
=24 m
I don't know sorry kid
Step-by-step explanation:
The volume of a box is the product of its dimensions
The volume of the box is 11 unit cube
<h3>How to determine the volume</h3>
From the question, we have the following highlights
- The cubes are unit cubes
- The boxes are packed without gaps
The volume of a unit cube is:
Volume = 1 unit cube
There are 11 cubes in the box. So, the volume of the box is:
Volume = 11 *1 unit cube
Volume = 11 unit cube
Hence, the volume of the box is 11 unit cube

Answer:
C
Step-by-step explanation:
We have the equation:
Add 10 to both sides to isolate the equation.
This is not factorable*, so we can use the quadratic formula:
In this case, <em>a</em> = 4, <em>b</em> = 5, and <em>c</em> = 10.
Substitute:
Simplify:
Since we cannot take the root of a negative, we have no real solutions.
Our answer is C.
*To factor something in the form of:
We want two numbers <em>p</em> and <em>q</em> such that <em>pq</em> = <em>ac</em> and <em>p</em> + <em>q</em> = <em>b</em>.
Since <em>ac</em> = 4(10) = 40. We need to find two whole numbers that multiply to 40 and add to 5.
No such numbers exist, so the equation is not factorable.
