When ur polynomial has more then one variable....and this one does...the degree is the highest term degree

7a^3b^2 ....this term has a degree of 5
2a^4...this term has a degree of 4
4b....this term has a degree of 1
15....this term has a degree of 0

so the highest degree term has a degree of 5....so that is the degree of this polynomial.

now if u just had 1 variable, the degree would be the highest exponent

a family has two cars. the first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of
nikklg [1K]

Car A consumes 25 gallon and car B consumes 15 gallon.

Step-by-step explanation:

Given,

The fuel efficiency of car A = 20 miles per gallon.

The fuel efficiency of car B = 15 miles per gallon.

In a week, two cars went 725 miles and consumed 40 gallons.

To find the consumption of each car in that week.

Let,

Car A consumed x gallon

Car B consumed y gallon.

According to the problem,

x+y = 40 ----- (1)

20x+15y = 725

or, 4x+3y = 145 -------- (2)

From (1) we get, x = 40-y

Putting the value of x in (2) we get,

4(40-y)+3y = 145

or, 160-4y+3y = 145

or, -y = 145-160

or, y = 15

From (1) we get, x = 40-15 = 25

Hence,

Car A consumes 25 gallon and car B consumes 15 gallon.

Which statement is true about the angle bisectors of a triangle?
Rashid [163]

Answer:

Follows are the solution to the given question:

Step-by-step explanation:

There are missing details, which is why its solution is as follows:

When an angle bisector points so, its two sides of the corner are equidistant. Its corner bisector of a triangle angle is a straight line splitting its angle into two congruent directions. In such a single point, calling its incentives, follow three-angle engineers are required of its three triangle angles.

What is f(5) if f(1) = 3.2 and f(x + 1) = (f(x))?
scoray [572]

Answer:

The value of f(5) is 3.2.

Step-by-step explanation:

It is given that f(1) = 3.2 and

f(x+1)=f(x)

Substitute x=1 in the above equation.

f(1+1)=f(1)

f(2)=3.2

Substitute x=2 in the given equation.

f(2+1)=f(2)

f(3)=3.2

Substitute x=3 in the given equation.

f(3+1)=f(3)

f(4)=3.2

Substitute x=4 in the given equation.

f(4+1)=f(4)

f(5)=3.2

Therefore the value of f(5) is 3.2.

ΔPQR has angle measurements of 80°, 50°, and 50°. What kind of triangle is ΔPQR?
trasher [3.6K]

Answer:

Isosceles Triangle; Acute Triangle

Step-by-step explanation:

Review your definitions of the different types of triangles:

acute triangle- a triangle that has three acute (less than 90 degrees) angles

obtuse triangle- a triangle that has an obtuse (greater than 90 degrees) angle.

right triangle- a triangle that had one right (90 degrees) angles

isosceles triangle- a triangle with two congruent sides and one unique side and angle.

equilateral triangle-  a triangle with three congruent sides and three congruent angles.

scalene triangle- a triangle with no congruent sides and no congruent angles.

With these definitions, we can classify ΔPQR as an isosceles acute triangle.
