Tbh i dont really remember how to this this but the only way i could think of solving it is saying how a spuare/rectangle have all equal sides so if they have all equal sides you can divide that number by 4 so 4/30=7.5 so i would say x = 7.5 tell me if its wrong

~ Good Luck :D ~

Area is length x width so:
(x+1)x=30
x^2+x-30=0
(x+6)(x-5)=0
x=-6, or 5. Only +5 makes sense.
So if x=5 then x+1=6 and you see that indeed 5*6=30

A state transportation worker records the number of miles traveled on a thruway and the corresponding tolls. The worker creates

ad-work [718]

Suppose the toll is $10. Then, .04m + 1.26 = 10. We can simplify that to .04m = 8.74 and again to m =218.5. Now, suppose the toll is $11. Then, .04m + 1.26 = 11. Going through the same steps as before we find that m = 243.5. So a $10 fair will allow a passenger to travel 218.5 miles while an $11 fare will allow 243.5 miles of travel. The difference between these two is 25 miles. Since the fares are $1 apart, that means each additional $1 increase results in 25 additional miles. More simply, 0.04m gives the slope of the line telling us how many miles are traveled per dollar of fare, which is to say 0.04. So we could divide 1 by .04 to get the same result.

How to prove its congruent

Katen [24]

There are five ways to find if two triangles are congruent: SSS, SAS, ASA, AAS and HL.SSS (side, side, side) SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. ... SAS (side, angle, side) ... ASA (angle, side, angle) ... AAS (angle, angle, side) ... HL (hypotenuse, leg)

The average radius of Jupiter is 4.34 x 10^4 miles. The average sun radius of the sun is 4.32 x 10^5. How many times greater is

Oksanka [162]

Answer:

The average radius of sun is approximately 9.95 times the average radius of Jupiter.

Step-by-step explanation:

We are given the following in the question:

Average radius of Jupiter =

$4.34\times 10^{4}\text{ miles}$

Average radius of the sun =

$4.32\times 10^{5}$

Relation between average radius of sun and average radius of Jupiter =

$\displaystyle\frac{\text{Average radius of Sun}}{\text{Average radius of Jupiter}}\\\\= \frac{4.32\times 10^{5}}{4.34\times 10^{4}}\\\\\displaystyle\frac{\text{Average radius of Sun}}{\text{Average radius of Jupiter}} = 9.953917\\\\\text{Average radius of Sun} \approx 9.95\times \text{(Average radius of Jupiter)}$

Thus, the average radius of sun is approximately 9.95 times the average radius of Jupiter.
