BRAINLY!!!- if a=7, b=8, and c=9.2 is this a right triangle? why?

Travka [436]

Answer:

Step-by-step explanation:

If this were a right triangle we would assume the Pythagorean Theorem to prove it

$a^{2} +b^{2} =c^{2}$

$7^{2} +8^{2} =9.2^{2}$

this gives us

49+64=84.64

this is 143=84.64 and therefore not equal and not a right triangle

Suppose the man in the St. Ives poem has x wives, each wife has x sacks, each sack has x cats, and each cat has x kits. Write an

marishachu [46]

Answer: $x+x^2+x^3+x^4$

Step-by-step explanation:

As per given,

Number of wives = $x$

Number of sacks = $x (\text{Number of wives} )= x\times x = x^2$

Number of cats = $x(\text{Number of sack})$ $= x \times x^2=x^3$

Number of kits = $x(\text{Number of cats} )=x\times x^3=x^4$

Now , the total number of kits, cats, sacks, and wives going to St. Ives = $x+x^2+x^3+x^4$

Hence, the required ex[pression: $x+x^2+x^3+x^4$

Please answer!! it’s 12:08 am and i’m trying to get these two questions done

Elena-2011 [213]

Answer:

21 and 14

Step-by-step explanation:

The relationship between x and y is proportional thus the equation is

y = kx ← k is the constant of proportion

To find k use the ordered pair y = 84 when x = 28 , then

84 = 28k ( divide both sides by 28 )

k = 3

y = 3x ← equation of proportion

When x = 7 , then

y = 3 × 7 = 21 ← value required in top table

When y = 42 , then

42 = 3x ( divide both sides by 3 )

x = 14 ← value required in lower table
