Answer:

X=3/2 or 1.732

Step-by-step explanation:

X^2-4+1=0

Combine like terms

-4 + 1 = -3

X^2-3=0

add 3 to both sides

X^2= 3

X= 3/2

Evaluate √ 9.6230 * 2.340 / 5.3 10 * 3.721​
adoni [48]

Answer:

\sqrt{15.76}

Step-by-step explanation:

\sqrt{9.6230 \frac{2.340}{5.310}3.721 }

Lets solve the fraction first

\frac{2.340}{5.310} =0.44

9.6230 x 0.44 = 4.23

4.23 x 3.721 = 15.76

\sqrt{15.76}

The sum of two numbers is 36. Twice the first number minus the second 6. Find the number.
just olya [345]

Answer:

14 AND 22

Step-by-step explanation:

LET THE LARGER NUMBER BE X AND SMALLER BE Y

X + Y = 36 …….1

2X – Y = 6…… 2

WE SOLVE SIMULTANOUSLY  

ADDING EQATION 2 AND 1

2X + X  + Y + (-Y) = 36 + 6

3X + Y – Y = 42

3X = 42

DIVIDING EACH TERM BY 3

3X/3 = 42/3

X = 14

THEN PUTTING X = 14 IN EQUATION  1

14 + Y = 36

Y = 36 – 14  

Y = 22
