The product of two consecutive integers is 420 an equation is written in standard form to solve for the smaller integer byfactoringwhat is the constant of the quadratic expression in this equation? x2 +x+0

Explanation:

if we call the fist of the numbers , then the following number is .

the product of this two numbers according to the problem is:

which results in:

The standar form of a quadratic equation is

so we must make the equation equal to zero:

and this way we can see that the constant in the quadratic expression is .

if you want the values of the consecutive numbers, they are 20 and 21.

answer; (c) the product does not cost the price shown in the advertisement; i believe this is correct; /// plz check   first good luck

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
