For the fiction f(x)=x^2+3x-28 solve the following f(x) = 0

Step-by-step explanation:

First, we need to set up the equation

To solve this, we have two options: factoring or using the quadratic formula. In this case, factoring will work, so we can use that

To factor, we need to find two numbers that add together to give you 3 and multiply to give you -28

In this case, these two numbers would nee to be -4 and 7

This means that our factored equation would be:

Now all we need to do is input the values of x that will give you 0. This means that the two solutions are

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
