no they are both incorrect by my understanding of your question use the Pythagorean theorem a^2 + b^2 =c^2 therefore 7^2 +x^2 = 13^2 or 49+x=169 then solve normally 169-49=120 √120 =5

The answer is 5

Sheridan is correct. She followed all of the correct steps of the Pythagorean Theory. The reason that Jayden was wrong is because he used the hypotenuse of the triangle as "b" in the formula instead of using it as "c" which is where they hypotenuse always has to go in this formula.

The cost of a customer smartphone bill can be modeled by the equation c=10g+50

Vika [28.1K]

Answer:

c=10(g+5)

Step-by-step explanation:

Given that,

The cost of customer smartphone bill is given by the equation as follows :

c=10g+50

Where

g is the number of gigabits of data the customer per month

We need to factor this cost polynomial

The common between 10 and 50 is 10

Taking 10 common. So,

c=10(g+5)

Hence, the required factor is equal to c=10(g+5).

Triangle ABC was dilated using the rule Do.4. Triangle

pshichka [43]

Answer:

The correct option is B. The length of OB' is 3 units.

Step-by-step explanation:

The rule of dilation is D₀,₄. It means dilation by scale factor 4 with center of dilation is origin.

$\text{Scale factor}=\frac{\text{Distance between center and any point of the image}}{\text{Distance between center and corresponding point of the Preimage}}$

$\text{Scale factor}=\frac{OB'}{OB}$

$4=\frac{OB'}{\frac{3}{4}}$

$4\times \frac{3}{4}=OB'$

$3=OB'$

The length of OB' is 3 units. Therefore the correct option is option is B.

Write the following equation in standard form. Then solve. 8q^2-5q=7q^2-8q+10

Nata [24]

You have to add the like terms in the equation
These like terms are 8q^2 and 7q^2 because they both share q^2

The other like terms are -5q and -8q because they both have ‘q’

So add them and then add extra numbers (the 10) to the equation

Hope this helps xo
