Can someone help me on this geometry problem & explain ?

lakkis [162]

If PQRS is a square.

Then |SP| = |PQ| = |QR| = |SR| and |PR| = |SQ|.

$\triangle PSR\ \text{is a right triangle}.\\\\\text{Let}\ |SP|=|SR|=x.\\\\\text{We can use the Pythagorean theorem:}\\\\|SP|^2+|SR|^2=|PR|^2\\\\\text{Substitute}\\\\x^2+x^2=14^2\\\\2x^2=196\qquad|\text{divide both sides by 2}\\\\x^2=98\to x=\sqrt{98}\\\\x=\sqrt{49\cdot2}\\\\x=\sqrt{49}\cdot\sqrt2\\\\\boxed{x=7\sqrt2}$

$|ST|=\dfrac{1}{2}|PR|\to|ST|=\dfrac{1}{2}\cdot14=7$

$Answer:\ ST=7;\ QR=7\sqrt2$

You can use the formula of a diagonal of a square

a - side of a square

d - diagonal of a square

$d=a\sqrt2$

d = 14

$a\sqrt2=14\qquad|\cdot\sqrt2\\\\2a=14\sqrt2\qquad|:2\\\\a=7\sqrt2$

Which two points satisfy y = -x2 2x 4 and x y = 4?

matrenka [14]

I will assume that the two equations are

1) y = -x^2 +2x + 4 and 2) x +y = 4

subtract 2 from 1 and you get

y -x - y = -x^2 + 2x + 4 - 4

-x = -x^2 +2x

x^2 -x -2x = 0

x^2 - 3x = 0

x(x-3)=0

x=0 and x - 3 =0

x=0 and x = 3

Then y = 4 - x

y = 4 - 0 and y = 4 -3
y = 4 and y =1

Solutions:

Points (0,4) and (3,1)
