Answer:

k=\frac{2P}{x^{2}}

Step-by-step explanation:

<u><em>The question is</em></u>

Which equation should she use?

we have the formula

P=\frac{1}{2}kx^{2}

Solve for k

That means ----> isolate the variable k

Multiply by 2 both sides

2P=kx^{2}

Divide by x^2 both sides

\frac{2P}{x^{2}}=k

Rewrite

k=\frac{2P}{x^{2}}

HELP ME ILL FRIEND U OR WHATEVER ANYTHING JUST HELP
Nataliya [291]

Answer:

91.5 ft

Step-by-step explanation:

AS = BH AS= area of square

AS = (14) (6)

AS = 84

7ft + 4ft = 11ft

14ft - 11ft = 3ft

base of the triangles = 3ft

AT = BH/2 AT = area of triangle

AT = (3)(5)/2

AT = 7.5

TA = 84 + 7.5 TA = total area

TA = 91.5
