How many solutions can be found for the linear equation? 4(x + 5) - 5 = 8x + 18/ 2

mylen [45]

Answer: The correct option is A.

Explanation:

The given equation is,

$4(x+5)-5=\frac{8x+18}{2}$

Multiply both sides by 2.

$2[4(x+5)-5]=\frac{8x+18}{2}$

$8(x+5)+2(-5)=8x+18$

$8x+40-10=8x+18$

$8x+30=8x+18$

Subtract both sides by 8x.

$30=18$

This statement is false for any value of x, therefore the system of equation have no solution and option A is correct.

What is the length of a hypotenuse when the legs are 5 and 12

Alisiya [41]

By using pythagoras theorem where
(Base)^2 +(perpedicular)^2 = (hypotenuse)^2
So,
(5)^2 +(12)^2 = (hypotenuse)^2
25 + 144 = (hypotenuse)^2
169 = (hypotenuse)^2
13 = hypotenuse

So, hypotenuse = 13
