6(7a-10) how do I solve this

Answers

Answer 1

Answer: $6(7a-10) \n \n 6 * 7a + 6 * -10 \ / \ distribute \n \n 42a + 6 * -10 \ / \ simplify \n \n 42a + -60 \ / \ simplify \n \n 42a - 60 \ / \ simplify \n \n Answer: \fbox {42a - 60}$

Answer 2

Answer: solve the brackets, to do that you should multiply the numbers inside the bracket with the first number outside and in the right to the brackets.so,

6(7a-10)= 42a-60
hence the answer is, 42a-60

Find all values of c that will make the polynomial a perfect square trinomial. Options: c = 49 c = 100 c = 144 c = 169

Answers

Answer :

All values of $ c $, specifically $ c = 49, 100, 144, $ and $ 169 $, can make a polynomial a perfect square trinomial depending on the other terms of the polynomial.

Step-by-step explanation :

1. Understanding Perfect Square Trinomials :

A perfect square trinomial is one that can be written in the form:

\[ (ax + b)^2 = a^2x^2 + 2abx + b^2 \]

From this formula, the value $ c $ would be equivalent to $ b^2 $, and the coefficient of the linear term (the term with $ x $) would be $ 2ab $.

2. Analyzing Given Options :

- Option 1 : c = 49

For $ c = 49 $, $ b^2 = 49 $ which implies $ b = \pm 7 $. The middle term would then be $ 2a(7) = 14a $.

- Option 2 : c = 100

For $ c = 100 $, $ b^2 = 100 $ which means $ b = \pm 10 $. The middle term would then be $ 2a(10) = 20a $.

- Option 3 : c = 144

For $ c = 144 $, $ b^2 = 144 $ which translates to $ b = \pm 12 $. This makes the middle term $ 2a(12) = 24a $.

- Option 4 : c = 169

For $ c = 169 $, $ b^2 = 169 $ which gives $ b = \pm 13 $. Consequently, the middle term would be $ 2a(13) = 26a $.

3. Conclusion :

Without specific details on the polynomial or its middle term, we can deduce that any of the provided options for $ c $ can result in a perfect square trinomial if the linear term of the polynomial matches the $ 2ab $ value corresponding to that $ c $.

Answers

Answer:

Para multiplicar 225 por 17, puedes utilizar el método de la multiplicación estándar. Aquí está el procedimiento paso a paso:

lua

225

× 17

--------

225 (225 multiplicado por 7)

+ 2250 (225 multiplicado por 1 y luego desplazado un lugar a la izquierda)

--------

3825

Por lo tanto, 225 multiplicado por 17 es igual a 3825.

The length of a rectangle is 2 more than 3 times the width. If the perimeter is 100 meters, what is the width of the rectangle?a. 13 meters
b. 12 meters
c. 11 meters

Answers

Answer: 12 meters

Step-by-step explanation:

Let the width of the rectangle be w.

Then the length of the rectangle will be 2+3w

We know that the perimeter of a rectangle is given by :-

$\text{P}=2(l+w)$ , where l is length and w is width of the rectangle.

Now, according to the question, we have

$2(w+2+3w)=100\n\n\Rightarrow2(2+4w)=100\n\n\Rightarrow\ 4+8w=100\n\n\Rightarrow\ 8w=96\n\nRightarrow w=12\ \text{meters}$

Hence, the width of the rectangle = 12 meters

The correct answer is 12 meters. Hope that helps!

NO, because in order to find the area of a circle you need to multiply pi with radius squared.
