Answer:

B. 1010

Step-by-step explanation:

Simplify:

(ab0+ab0ab) ÷ (ab) - 1

Note that:

ab = 10a +b
ab0 = 10* (10a + b) = 10ab
ab0ab = 1000ab + ab = 1001 ab

Therefore:

(ab0+ab0ab) ÷ (ab) - 1 =
(10ab + 1001ab) ÷ (ab) - 1 =
(1011ab) ÷ (ab) - 1 =
1011 - 1=
1010

Correct choice is B.1010

(2x+4)^2 - (x-5)^2 = 26x Please solve (explained)

Zina [86]

Expand the squared binomials:

$(2x+4)^2=4x^2+16x+16$

$(x-5)^2=x^2-10x+25$

Then

$(4x^2+16x+16)-(x^2-10x+25)=3x^2+26x-9=26x$

$\implies3x^2-9=0$

$\implies3x^2=9$

$\implies x^2=3$

$\implies x=\pm\sqrt3$
