Answer:

Both students are correct because polynomials can be grouped in different ways to factor. Both ways result in a common binomial factor between the groups. Using the distributive property , this common binomial term can be factored out. Each grouping results in the same two binomial factors.

Step-by-step explanation:

6 use fermat’s theorem to find a number x between 0 and 28 with x85 congruent to 6 modulo 29. (
Ulleksa [173]
If

x^{85}\equiv6\mod29

then we have

\dfrac{x^{85}}6\equiv1\mod29

By Fermat's little theorem, if a is not divisible by a prime p, then

a^{p-1}\equiv1\mod p

This works for x=6; in this case, we would have

\dfrac{6^{85}}6=6^{84}=\left(6^3\right)^{28}=\left(6^3\right)^{29-1}\equiv1\mod29

Joy makes 6.5 litres of soup, correct to the nearest 0.5 litre. She serves the soup in 280 ml portions, correct to the nearest 1
Levart [38]

Answer:

Joy definitely does have enough soup for 22 people.


Step-by-step explanation:

Upper Bound: 285ml  turn it to 0.285 L                      10÷2=5

280ml  :

Lower Bound: 275ml turn it  to 0.275 L

Upper Bound: 6.75 L                           0.5÷2=0.25

6.5 Litters  :

Lower Bound:6.25  L

6.75÷0.275=24.54 or 25  

6.25÷0.285=21.92 or 22

7. If SK = 13x - 5, KY= 2x + 9, and SY = 36-x, find each value.
sweet [91]

Answer:

SY=34, SK=21 and KY=13

Step-by-step explanation:

we have that

SY=SK+KY

substitute the given values

(36-x)=(13x-5)+(2x+9)

solve for x

36-x=15x+4

15x+x=36-4

16x=32

x=2

<em>Find the value of SY</em>

SY=(36-x)=36-2=34

<em>Find the value of SK</em>

SK=(13x-5)=13(2)-5=21

<em>Find the value of KY</em>

KY=(2x+9)=2(2)+9=13

Which of the following is a radical equation? x + StartRoot 5 EndRoot = 12 x squared = 16 3 + x StartRoot 7 EndRoot = 13 7 Start
d1i1m1o1n [39]

Answer:

x = 3

Step-by-step explanation:

(8x-8)^{3/2}=64

Multiply both sides by the exponent 2/3.

8x - 8 = 64^{2/3}

Solve for the exponent.

8x-8=16

Add 8 to both sides.

8x = 16+8

8x=24

Divide 8 into both sides.

x=24/8

x=3
