Answer:

16

Step-by-step explanation:

10/a = 15/24

Cross multiply.

15 × a = 10 × 24

15a = 240

Divide both sides with 15.

a = 240/15

a = 16

Answer:

a = 16

Step-by-step explanation:

=> \frac{10}{a} = \frac{15}{24}

Cross Multiplying

=> 10 * 24 = a * 15

=> 15a = 240

Dividing both sides by 15

=> a = 16

-4 + x                        2 + y
-------  =  5  and         ------  = 5
   2                               2

so x = 10 + 4 = 14  and y = 10 - 2 = 8

endpoint N = (14,8)

Please help thank you.
Mnenie [13.5K]

Answer:

Option D

Step-by-step explanation:

Whenever we take a square root of a number the ± sign is with it like here in the question

x^2=20\\\\Apply\ square\ root\ on\ both\ sides\\sqrt{x^2}=\sqrt{20}  \\\\The\ square\ cancels\ out\ with\ the\ root\x=\sqrt{20}

And then x = ±4.47 which means x has two values one is +4.47 and the other is -4.47 so Option D is our answer.
