Evaluating a function means to plug the required value, substituting every x occurrence with that value.

So, you have

f(x)=3x^2+80x \implies f(2) = 3\cdot 2^2+80\cdot 2 = 3\cdot 4 + 160 = 12+160=172

How many square meters in a room of such dimensions 5/3/4?
sdas [7]

Answer: 3.75 Square Meters

Step-by-step explanation: I am not sure exactly what you asked for here, I chose to take it as the one wall being 5 meters long, and the other being 3/4 meter long. If this was the right senario, then what you would do to solve it, and what I did, is just multiply 5*3/4 or if it makes it simpler, 5*.75

Answer:

Option B.

a

Step-by-step explanation:

Given:

-3( -x + a ) + 7 < 5     When x = -1

To Find:

a ?

Solution:

-3( -x + a ) + 7 < 5     When x = -1

Substitute x = -1 in above  we get

-3(-(-1) + a ) + 7 < 5

-3(1 + a) < 5 - 7

Using Distributive Property we get i.e A(B+C) = AB + AC

\therefore -3\times 1 +(-3)\times a

guapka [62]

Answer:

Please mark be brainliest and I hoped this helped!

x = 45°

Step-by-step explanation:

Since this is an isosceles triangle, that means that x, and the angle opposite from x, are the same. We take 135° and subtract that from 180°. That gives us 45°. Since the angle opposing x is 45°, then x is 45° as well.
