Encuentra en cada producto notable el error o errores,enciérralo y escribe el resultado correcto.

lbvjy [14]

Given:

The equation is:

$(2x+3y)(2x-3y)=4x^2+6y^2$

To find:

The error in the given equation and correct it.

Solution:

We have,

$(2x+3y)(2x-3y)=4x^2+6y^2$

Taking left-hand side, we get

$L.H.S.=(2x+3y)(2x-3y)$

$L.H.S.=(2x)^2-(3y)^2$ $[\because a^2-b^2=(a-b)(a+b)]$

$L.H.S.=(2)^2(x)^2-(3)^2(y)^2$ $[\because (ab)^x=a^xb^x]$

$L.H.S.=4x^2-9y^2$

It is not equal to right-hand side $4x^2+6y^2$ . In the right hand side, there must be a negative sign instead of positive sign.

Therefore, $(2x+3y)(2x-3y)=4x^2-6y^2$ .

A first number plus twice a second number is 13. Twice the first number plus the second totals 14. find the numbers

sashaice [31]

Answer:

the first number is 5 the second number is 4

Step-by-step explanation:

first number = x

second number = y

X+2y=13 given this isolate x x = 13-2y

2x+y=14 substitute 13-2y for x

2(13-2y)+y=14

26-4y+y=14

-3y=-12

y=4 taking this number substitute into either equation above

x+2(4)=13

x+8=13

x=5
