4.

The sum of three consecutive multiples of 8 is 888. Find the multiples.

Answer»

ANSWER:

LET 3 CONSECUTIVE multiples of 8 be

8x, 8(X+1), 8(x+2)

-> By the given terms

8x + 8(x+1) + 8(x+2) = 888

8(x + x + 1 + x + 2)= 888

3x+3= 888

8

3x+3 = 111

3x=111-3

3x= 108

x= 108

3

x= 36

8x=36×8=288

8(x+1)= 8×36+1

=8+37

=296

8(x+2)=8×36+2

=8×36+2

=309

Answer» Answer: Read the whole answer after which mark me brainiest or follow. Step-by-step explanation: There are some properties associated with a perfect square A perfect sq has its units digit ENDING with 0,1,4,5,6,9 not 2,3,7,8 so ii and iii 1458 & 2028 are not a perfect sqr{ending with 8} A perfect sqr has 2n no. of zeroes(even no. basically ) So i 180 is not a perfect sqr {ODD no. zero(1)} if unit digit has 4 or 6 perfect sq will have 6 as unit digit not applicable so what's applicable we can apply these for all no.s but other properties are faster..... A perfect sqr leaves 0 or 1 as a REMAINDER when divided by 3 A perfect sqr leaves 0 or 1 as a remainder when divided by 3252%3 (remainder) =0 or 1 :-D or ;-) for any perfect sqr(n+1)² - n² = n+1 +n 252² -251²= 252+251 =503 So only 252 is a perfect square roughly 15.8745078664² Make me brainliest if you want to thank me and give you answers: logical

Which of the following are perfect square:180,2028,1458,252

Answer»

Answer:

Read the whole answer after which mark me brainiest or follow.

Step-by-step explanation:

There are some properties associated with a perfect square

A perfect sq has its units digit ENDING with 0,1,4,5,6,9

not 2,3,7,8

so ii and iii 1458 & 2028 are not a perfect sqr{ending with 8}

A perfect sqr has 2n no. of zeroes(even no. basically )

So i 180 is not a perfect sqr {ODD no. zero(1)}

if unit digit has 4 or 6 perfect sq will have 6 as unit digit

not applicable

so what's applicable

we can apply these for all no.s but other properties are faster.....

A perfect sqr leaves 0 or 1 as a REMAINDER when divided by 3

A perfect sqr leaves 0 or 1 as a remainder when divided by 3252%3 (remainder) =0 or 1

:-D or ;-)

for any perfect sqr(n+1)² - n² = n+1 +n

252² -251²= 252+251 =503

So only 252 is a perfect square

roughly 15.8745078664²

(x^3+6x^2+12+13x)÷(x+3)

Answer»

Answer:x=3

x=23−−7

=23−i7

=1.5000−1.3229i

x=23+−7

=23+i7

=1.5000+1.3229i

Step-by-step explanation:(1): "x2" was REPLACED by "x^2". 1 more similar replacement(s). (((x3) - (2•3x2)) + 13x) - 12 = 0

2.1 x3-6x2+13x-12 is not a perfect cube 2.2 FACTORING: x3-6x2+13x-12
