L=6+W
A=LW
sub 6+W for L
A=(6+W)(W)
expand
oh, A=50
50=W²+6W
minus 50 both sides
0=W²+6W-50
we gots to use quadratic formula
for
aW²+bW+c=0
W=
we got
a=1
b=6
c=-50
W=
W=
W=
W=
W=
W=
or W=
aprox
W=-10.6811 or W=4.68115
can't be negative width
width=4.68115 or -3√59
Answer: the awnser is 9, 40, 41 mark me brainlist
Step-by-step explanation:
Sum of the squares of the two side = Square of longest side
a² + b² = c²
a)
So let's check 7, 24, 25
Is 7² + 24² = 25² ?
7*7 + 24*24
49 + 576
=625.
Let us perform the other side 25²
25² = 25 * 25 = 625
Therefore the left hand side = Right hand side.
Therefore 7, 24, 25 is a Pythagorean Triple
b)
Let's check 9, 40, 41
Is 9² + 40² = 41² ?
9² + 40²
9*9+ 40*40
81 + 1600
=1681
Let us perform the other side 41²
41² = 41 * 41 = 1681
Therefore the left hand side = Right hand side.
Therefore 9, 40, 41 is a Pythagorean Triple.

Answer:
slope is (-7/4) and y-intercept is 7
Step-by-step explanation:
If we convert the equation 7x + 4y = 28 into Slope-intercept form, we can find the slope and the y-intercept.
7x + 4y - 7x = 28 - 7x
4y = 28 - 7x
divide both sides by 4
y = (28 - 7x)/4
y = 7 - 7x/4
slope is (-7/4) and y-intercept is 7
