Solve.<br> 4(y + 4) = 32

MakcuM [25]

Answer:

y = 4

Step-by-step explanation:

4*y = 4y

4*4 = 16

4y+16=32

to get 4y alone, we subtract 16 from 32.

32-16 = 16

4y = 16

to get y alone, we divide 4 by 16

16/ 4 = 4

so, y = 4

Use the given figure to find the length of x.

lubasha [3.4K]

Answer:

x = 18

Step-by-step explanation:

This problem can be solved using concept of Pythagoras theorem.

Pythagoras theorem states that in a right angled triangle, if "a" and "b" are sides containing the right angle and h is hypotenuse then the relation between them is $a^2 + b^2 = h^2$

_________________________________________

Given in the problem

a = 24

b = x

h = x+12

applying Pythagoras theorem

$24^2 + x^2 = (x+12)^2\\=> 576 + x^2 = x^2 + 24x + 144\\=>576 = x^2 + 24x + 144 - x^2\\=> 576 = 24x + 144 \\=> 576 - 144= 24x\\=> 432 = 24x\\=> x = 432/24 = 18$

for (x+12)^2 we have used formula $(a+b)^2 = a^2 + 2ab + b^2$

Thus, value of x is 18.
