Answer:
B. 8 cm.
Step-by-step explanation:
The area of a rectangle is the length*width.
The area of the larger rectangle is 4*12=48.
The area of the smaller rectangle is 3*x=3x.
If the larger rectangle's area is twice that of the smaller rectangle, then we can say 48=2*3x.
Let's solve for x
48=2*3x
48=6x
x=8
Each of the figures are similar. Find the missing length
Answer:
63
Step-by-step explanation:

so 7x9 is 63
y=2x^2+12x+14 in vertex form
Answer:
y = 2(x + 3)² - 4
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square
y = 2x² + 12x + 14 ← factor out 2 from the first 2 terms
= 2(x² + 6x) + 14
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = 2(x² + 2(3)x + 9 - 9 ) + 14
= 2(x + 3)² - 18 + 14
= 2(x + 3)² - 4 ← in vertex form

find the length of side x using the Law of Cosines.
Answer:
The length of side x is 22.91
Step-by-step explanation:
As per law of cosine
[tex]X = \sqrt{a^2 + b^2- 2*a*bcos\gamma}[/tex]
Where
[tex]gamma = 56[/tex] degrees
a = 20
b = 27
Substituting the given values in above equation, we get -
[tex]X = \sqrt{20^2 + 27^2 - 2*20*27*cos 56} \\X = 22.91[/tex]
Hence, the length of side x is 22.91

ASAP someone please use the Pythagorean Theorem to solve for the missing side of these two right triangles.
Answer:
9) x = 5
10) x = 4
Step-by-step explanation:
a^2 + b^2 = c^2
9) 6^2 + x^2 = 8^2
- 36 + x^2 = 64
- 36 - 36
_______________
x^2 = 28
Square root them
Squareroot x^2 is x
Square root 28 is 5.29 round is 5
so x = 5
*Correct me if im wrong*
10) 3^2 + x^2 = 5^2
9 + x^2 = 25
- 9 - 9
____________________
x^2= 16
Square root them
square root of x ^2 is x and square root of 16 is 4
so x = 4

Are the ratios 18:9 and 2:1 equivalent?
Answer:
Yes
Step-by-step explanation:
[tex]\frac{18}{9} =\frac{2}{1}[/tex]
The two ratios are,
→ 18 : 9 and 2 : 1
We have to find,
→ whether the ratios are equivalent?
Now simplify the first ratio,
→ 18(÷9) : 9(÷9) = 2 : 1
→ 2 : 1 = 2 : 1
Yeah, the two ratios are equivalent.

mb- The graph shows the relationship between time and the number of soda bottles a machine can make. Use the points (2,100) and (4,200) to find the number of soda bottles the machine can make each minute
Answer:
1200
Step-by-step explanation:
We can gather from what's given that y=20xy represents the total number of bottles produced in the given time in seconds, which is x. When x=1, y=20, This means that each second the machine can make 20 soda bottles. Each minute is 60 seconds, so when x=60, y=20*60 =1200 soda bottles.
