Answer:-

Step-by-step explanation:

h(x) = x^2 + 2x -3

x = 2

h(2) = 2^2 + 2(2) - 3

h(2) = 4 + 4 - 3

h(2) = 8-3

h(2) = 5

x = - 4

h(-4) = (-4)^2 + 2(-4) - 3

h(-4) = 16 - 8 - 3

h(-4) = 16 - 11

h(-4) = 5

========

h(2) - h(-4)

5 - 5

The perimeter of a triangle is 65 meters. The second side is 5 meters less than the first side The third side is 7

tangare [24]

Answer:

The length of each side is 31.5m, 26.5m, 7m

Step-by-step explanation:

Let the length of the first side of the triangle be x meters.

Then, the second side is x-5 meters.

The third side is given as 7 meters.

The perimeter is 65 meters

This gives us the equation:

$65 = x + x - 5 + 7$

$65 - 7 + 5 = x + x$

$63 = 2x$

$x = \frac{63}{2} = 31.5$

The length of each side is 31.5m, 26.5m, 7m

malfutka [58]

Let's find the equation.
2,200×1.085^x=y
We need x to equal 6.
2,200×1.085^6=y
2,200×1.631467508843266
3,589.23
The balance after six years is $3,589.23.
