The sum of a positive number and its square is 20. find the number.

Answers

Answer 1

Answer: so x+x^2=20
subtract 20 from both sdies
x^2+x-20=0
factor
find what 2 nmbers multiply to get -20 and add to get 1

factors of 20=2 times 2 times 5
the combos are
2 times 10
4 times 5
1 times 20

4 and 5 are 1 in diference
5-4=1
5 times 4=20

(x-4)(x+5)=0
if xy=0 then x and/or y=0
set each to zero
x-4=0
add 4
x=4

x+5=0
subtract 5
x=-5
but you want positive so this is an extranius answer so discard this

the number is 4

Answer 2

Answer: the answer is 4

4 + 16 = 20

Lucas makes the statement: "The exterior angles of a triangle are always obtuse." Of the following, which provides a counterexample to the statement?

Answers

The given statement "The exterior angles of a triangle are always obtuse." is not always true.

The given statement is "The exterior angles of a triangle are always obtuse."

We need to provide a counterexample to the given statement.

What is an exterior angle?

The angle is formed by a polygonalside and its extended neighbouring side. When a transversal cuts one of two lines, it creates an angle that is outside of the line.

Take an obtuse-angled triangle as a counter-example:

An obtuse-angled triangle or obtuse triangle is a type of triangle whose one of the vertex angles is bigger than 90°. An obtuse-angled triangle has one of its vertex angles as obtuse and other angles as acute angles i.e. if one of the angles measure more than 90°, then the sum of the other two angles is less than 90°.

In the figure given below, we can see in ΔABC, ∠A=110°.

Exterior angle to ∠A measures 70°.

Therefore, the given statement "The exterior angles of a triangle are always obtuse." is not always true.

What is the equation of the line that passes through (0,3) and (7,0)

Answers

Answer:

y = (-3/7)x + 3

Step-by-step explanation:

As we go from (0,3) to (7,0), x increases by 7 from and y decreases by 3 to 0.

Thus, the slope of this line is m = rise / run = -3/7.

Subst. the appropriate values from this info into the slope-intercept form of the equation of a straight line:

y = (-3/7)x + 3 Note that the y-intercept is given: (0,3).
