Answer:

0=0 true for all x

Step-by-step explanation:

$2x+3\left(x-1\right)=7x+1-2\left(x+2\right)\\\\$

$2x+3x-3=7x+1-2\left(x+2\right)$

$5x-3=5x-3$

Hope this help ya

cow is tied to a tree on grazing land with a 9 -meter rope What is the longest distance around that it can cover ?

Sholpan [36]

Radius = 9m
Diameter = 18 m
Area = 254.34 squared m
Circumference = 56.52 m

I’m guessing is asking for the circumference because it says around

The function p(x) = x^3 is a polynomial. Here the “variable”, x, is being raised to some constant power. The function f(x)=3^x is an exponential function (the variable is the exponent).

Exponential functions tend to get very big very quickly, and though they start out smaller than polynomial functions, they will always eventually become bigger. Notice that the two functions meet at x = 2 and x = 4.

The quadrilateral shown is a rectangle. What is the measure of PR? (round to the nearest hundredth)

sladkih [1.3K]

Option B) 37.12 is the right answer

Step-by-step explanation:

It is given that the qudrilateral is a rectangle which means that opposite sides wil be equal and all interior angles will be 90 degrees

PS = 17

PQ = SR = 33

The diagonal PR will form a right-angles triangle with PR being the hypotenuse

So,

Base = SR = 33

Perpendicular = PS = 17

Hypotenuse = PR = ?

The Pythagoras theorem will be used to find the length of PR

So,

$H^2 = B^2+P^2\\(PR)^2 = (SR)^2 + (PS)^2\\PR^2 = (33)^2+(17)^2\\PR^2 = 1089+289\\PR^2 = 1378\\$

Taking square root on both sides

$\sqrt{PR^2} = \sqrt{1378}\\PR = 37.1214$

Rounding off to nearest 100th

PR = 37.12

Hence,

Option B) 37.12 is the right answer
