Step-by-step explanation:

X(x^2-3x-9)+5

(X+5)(x^2-3x-9)

Now

SOLVING (x^2-3x-9) by SHRIDHAR ACHARYA method

D = 9 - 4.1.-9

D= 9+36

D= 45

Now,

X=3+root45/2 or 3-root45/2

Thus FACTORS are = 5, 3+root45/2, 3-root45/2

Step-by-step EXPLANATION:

ANSWER:

Step-by-step explanation:

BREADTH = x

Then Length = 3 times of breadth.

lenght = 3x

Given that

The perimeter of the RECTANGLE =AREA of square = 625

perimeter of rectangle =2 (l+b)

625=2 (3x+x)

625/2=4x

625/2×4 = x

78.125 = x

Hence,

Area of rectangle = length × breadth

Area of rectangle = 3X × x

Area of rectangle = 3×78.125 × 78.625

Area of rectangle =18427.7 cm^2

ANSWER:

no.....

Step-by-step EXPLANATION:

NUMBER is 10

10+5=15

15×9=135

135-1=134

Answer:

270125

Step-by-step explanation:

TOTAL No. Of cards =52

No.Of cards for each suit = 13

Total types Of French suit = 4(hearts,spades, diamonds,clubs)

Prob. = Conditional case /total case

For this conditional case of SELECTING all FOUR same suit,it can be either hearts or spades or clubs or diamonds

So Total no. Of conditional case= no. of case of selecting all four cards of hearts suit +no.of case of selecting all four cards of spades suit +no.of case of selecting all four cards of clubs suit + no. of case of selecting all four cards of diamonds suit.

= 13C4+13C4+13C4+ 13C4

=4*(13C4)=2860

Total no. of case= 52C4=270725

So, probability of GETTING all four cards of the same suit=2860/270725

Answer:

Step-by-step explanation:

let age of son one yr ago be X

age of man one yr ago be 8x

.....

age of son after one year = x+1

age of man after one year = 8x+1

....

now accordind to question..

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

8x+1=x^2 + 1 +2x

after solving

8x = x^2 +2x

now...x^2 - 6x=0

solving this we get ...x=0 and x = 6 but

age CANT be zero...so..x=6...

age of son is x+1 = 7 years

and age of man be 8x+1= 49...ANS..

Answer:

We know that an isosceles triangle has two sides of the same length and ONE side of different length.

The sum of the measures of the ANGLES of the triangle is 180°.

We know the vertical angle of the triangle i.e., 100°.

Let the base angles be X and x since they have the same value.

So we get,

x+x+100=180° (by condition)

2x+100=180°

2x= 180-100

2x=80

x=80/2

x=40°

So the measure of both the base angles are x i.e., 40°.

Answer:

5 SECONDS

Step-by-step explanation:

420 = 16t^2+4t

16t^2+4t-420=0

4(4t^2+t-105)=0

4t^2+t-105=0

(4t+21)(t-5)=0

t = 5 & t = -5.25

Time cannot be NEGATIVE, THEREFOR t = 5 seconds

CONSIDER NO AS X

IF SEVEN TIMES A NUMBER

7X

DIDIDE BY 5

7x/5=y-5

Answer:

Step-by-step EXPLANATION:

Let the 1ST no. be =x

2nd = y

x/y = 5/6

Let x=5k nd y=6k. (K is constant)

2nd CASE. When 7 is subtracted

x-7/y-7 = 4/5

5k-7/6k-7 = 4/5

5k-7(5) / 6k-7(4) = 0

25k-35= 24k-28

K= 7

No. are 5k ie 5*7=35

6k ie 6×7=42
