HELP! 2 problems!
Anit [1.1K]

Answer:

 x=4   (solution)                             x=-14             (extraneous solution )

Step-by-step explanation:

|x+5|=9 -------original equation

Equation can be equal to +9   and -9

x+5 =9                           x+5 =-9

x= 9-5                            x=-9-5

 x=4   (solution)                             x=-14             (extraneous solution )

                                       

for checking  

x+5 = 9                                            x + 5=9

4+5= 9                                             -14+5=9

9=9                                                    -9=-9

140% of what number is 35?
Elodia [21]
In order to solve this, all you have to do is divide 35 by 1.4 (because you need to move the decimal places over to the left two places when changing from a percentage to a decimal.) When you do that, you get 25, so 35 is 140% of 25. I hope this helps! :)

Find AB. Round to the nearest tenth if necessary.<br>​
shusha [124]

Answer:

I think the right answer would be 7

Step-by-step explanation:

We got-ta use the equation: CA * BA = DA²

CA = 15 + BA

DA² = 8² = 64

=> (15 + BA) BA = 64

Subtract 15 from each side:

BA(BA) = 49

BA² = 49

Now take the square root of each side

BA = 7

Hope this helps!
