Solution:

Formula of perimeter = $2(W+H)$

So, 2W + 2H = 32.4 ... (1)

Ratio = 5:4

So, $\frac{W}{H} =\frac{5}{4}$

4W - 5H = 0 ... (2)

Solve equation (1) and (2).

W = 9.0 and H = 7.2

Use the Pythagorean theorem,

$W^{2} + H^{2} = D^{2}$

$D^{2} = (9.0)^{2} + (7.2)^{2}$

$D^{2} = 132.84$

D = 11.52

D = 11.5

Hence, the measure of diagonal is 11.5 inches.

Which is the simplified form of the expression (6-4)-9

Veseljchak [2.6K]

I'll give you a hint. You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtracting.

First you had to calculate with parenthesis first.

$(6-4)=2-9$

Then you add and subtract from left to right.

$2-9=-7$

Final answer $\boxed{=-7}$

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

Consider exponential function h. h(x) = 3x + 4

GarryVolchara [31]

The function is always positive.

(0,5) is the y-intercept, since the graphed line never crosses the x axis, there is no x-intercept.

The function is positive and greater than 4 for all values of x

Not sure what the actual choices are on a couple of the questions. The choices would help answering.
