Solve by completing the square. Round your answers to the nearest tenth and then locate the greater solution. +10x-7=0

Step-by-step explanation:

Step 1: Write our Givens

Move the constant term ,(the term with no variable) to the right side.

Here we have a negative 7, so we add 7 to both sides

Next, we take the linear coeffeicent and divide it by 2 then square it.

Then we add that to both sides

Next, we factor the left,

we got 5 because 5 add to 10 and multiply to 25 as well.

so we get

This is called a perfect square trinomial.

Next, we take the square root of both sides

± menas that we have a positive and negative solution.

Subtract 5 form both side so we get

The greater solution is when sqr root of 32 is positive so the answer to that is

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)
