(3t^2 + 2 + (-2)) + (t^2 + 3t - 4) - (4 + (-5))

Apply the distributive property to remove parentheses.

3t^2 + 2 - 2 + t^2 + 3t - 4 - 4 + 5

Combine like terms.

<h3>4t^2 + 3t - 3 is the simplified form of the given expression.</h3>

If f(x)=-2(5)^x what is f(2)

JulsSmile [24]

What the question is asking is for you to <em>evaluate the function f at x=2</em>, which means you'll need to substitute the x in the function for 2, giving you:

f(2) = -2(5)²

The interior angles formed by the sides of a pentagon have measures that sum to 540°. What is the measure of angle B?

patriot [66]

Answer:

m∠B = 110°

Step-by-step explanation:

We know that,

The sum of the measures of the angles in a pentagon is 540°.

So, we get,

130 + (x-5) + (x+30) + 75 + (x-35) = 540

i.e. 3x + (130+30+75) - (5+35) = 540

i.e. 3x + 235 - 40 = 540

i.e. 3x + 195 = 540

i.e. 3x = 540 - 195

i.e. 3x = 345

i.e. x= 115°

Now, as m∠B = (x-5)° = (115-5)° = 110°

Hence, the measure of angle B is 110°.
