You need to find the total surface area of the rectangular prism. The top and bottom are 8(6), which equals 48. Since we want both the top and bottom, multiple 48 by 2 to get 96. The we need to calculate the remaining 4 sides. Two of them are 15(6), which is 90. Again, multiply by two since there’s two of those sixes to get 180. Finally, the last two sides are 15(8), which is 120. Add all of these numbers together to get 96+180+120=396. So she will need 396 cm^2 of fabric.

What is the length of segment QV?

32 units
36 units
40 units
44 units

Answers

Answer:

44

Step-by-step explanation:

because i just did the test

The length of the segment in the given figure is 44 units.

Consider triangle STR and ΔQTR.

We have to find the length of QV.

∠TRQ = ∠TRS = 90°

TR = TR (Common)

SR = RQ (Given)

So, ΔTSR ≅ ΔTQR ( By SAS Congruence Criterion)

So, By CPCT (Correspondence part of congruent triangle)

TS = TQ

2x+8=40

2x=32

Divide both sides by 2

x=16

Now segment QV=3x-4

3(16)-4

48-4=44 units

Answer: Our required answer is 11(2c+3d)

Step-by-step explanation:

Since we have given that

22c + 33d.

We have to use "Distributive property" to factor out the greatest common factor.

Since we know that 11 is the greatest common factor of 22 and 33.

So, it becomes,11(2c+3d)

Hence, our required answer is 11(2c+3d)

Hello there! The value of x is 20 or -20

"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.

Step-by-step explanation:

[tex] \large{ \frac{ {x}^{2} }{ {5}^{2} } = {4}^{2} }[/tex]

First, we simplify 5² and 4²

[tex] \large{ \frac{ {x}^{2} }{25} = 16}[/tex]

Multiply the whole equation by 25 to get rid of the denominator.

[tex] \large{ \frac{ {x}^{2} }{25} (25) = 16(25)} \\ \large{ {x}^{2} = 400}[/tex]

Square both sides and solve the equation.

[tex] \large{ \sqrt{ {x}^{2} } = \pm{ \sqrt{400} }}[/tex]

Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.

[tex] \large{x = \pm{20}}[/tex]

Upon graduating, he went on to Cambridge University for postgraduate studies|in cosmology (the study of the universe). At age 21, Stephen started to stumble and drop things. His speech became slurred. Doctors diagnosed him with ALS, a disease that left him mostly paralyzed. His illness did not affect his brilliant mind.
