Answer:

5(x - 5y)(x + 5y)

Step-by-step explanation:

Note that 5 is common to both terms.  Thus,

5x² - 125y² = 5(x² - 25y²).

Also note that x² - 25y² is the difference of two squares and has factors (x - 5y) and (x + 5y).

In fully factored form, 5(x² - 25y²) is:

5(x - 5y)(x + 5y)

Solve :- Ques 5 ) (a) .
svp [43]

Answer:

Hey There!

Let's solve...

We have

\angle \: odb =  \angle \: cao \\  \\  \angle \: dbo =  \angle \: aco \\  \\

Using AA Criterion of Similarity we have

\triangle \: obd \:  -  \triangle \: oac \\  \\

This implies that

\frac{od}{ob} =  \frac{oa}{oc} \to \frac{6}{3 + 2 } \: or \:  \frac{6}{5} =  \frac{oa}{oc}    \\  \\  \to \: oa =  \frac{6}{5} oc

Now,

ab = ao - bo \\  \\  =  \frac{6}{5}oc - bo =  \frac{6}{5}(od - oc) \\  - bo \\  \\  =  \frac{6}{5}(6 + 4cm) - 5cm \\  \\  = 7cm

Note:Every letters should be in capital, i don't have any option here so i can't do.

Terry bought a sweater for$24 before tax he had a coupon for 1/4 off the sales tax rate was 6%. How much did terry pay for the s
Ira Lisetskai [31]

Answer: Terry paid  $18.36 for the sweater.

Step-by-step explanation:

Given: Sales price of sweater = $24

Coupon states \dfrac14 off the sales, i.e. Terry will get \dfrac14\times24=\$6 discount.

Also, tax rate = 6%

Tax will be charged = 6% of Sales price of sweater

=  0.06 x 6

= $0.36

Now , Final amount for Terry = Sales price - discount +tax

= $(24-6+0.36)= $18.36

Hence, Terry paid  $18.36 for the sweater.

What is the value of a?
Juli2301 [7.4K]
Actually, the answer is not A, if you're saying A is the first choice above.  That's incorrect.  You will need to use the Geometric mean for right triangles here to figure out what the value of a is.  We will use this form: \frac{YZ}{WZ} = \frac{WZ}{XZ}.  We have a value for YZ of 3; side a is XZ.  That means in order to solve this we need WZ, which we can find using pythagorean's theorem.  3^2 + 4^2 = c^2 and 9 + 16 = c^2 and c = 5.  Now we fill in accordingly: \frac{3}{5}= \frac{5}{XZ}.  Cross-multiply to get 3XZ=25 and side XZ is \frac{25}{3}.  XZ is 25/3 and YZ is 3, so 25/3 - 3 = XY.  That means that XY (side a) = 16/3 or 5 1/3, choice B, or the second one down.
