1 answer:

3 0

Let’s make an equation
Let’s say x = amount of years after
Smith = 8, mother = 42
3(8 + x) = 42 + x
24 + 3x = 42 + x
2x = 18, x = 9
Solution: after 9 years

$x^2+( 5\sqrt2-x)^2= (5\sqrt2)^2\\
x^2+50-10\sqrt2x+x^2=50\\
2x^2-10\sqrt2x=0\\
x^2-5\sqrt2x=0\\
x(x-5\sqrt2)=0\\
x=0 \vee x=5\sqrt2$

PLEASE ANSWER THIS FAST Will the red square and the orange square always equal the blue square? What colored square is the hypot

Vikentia [17]

Step-by-step explanation:

The area of the blue square will always equal the sum of the area of the orange and red rectangles

The pythagorian theorem:

a²+b² = c²

now let a be the side of the red triangle and b the side of the orange one

so a² is the area of the red triangle and b² is the area of the orange one

Let c be the side of the blue rectangle

so c² is the area of it

then what we concluded is right

the hypotenuse is the blue side since it is the larger one
