The product of (3p-7)(3p+7) is a. 9p^2-49

(3p - 7)(3p + 7) has the form of (a-b)(a+b).
So (a-b)(a+b)= a^2-b^2.
So in (3p - 7)(3p + 7), a=3p and b=7.
So (3p - 7)(3p + 7) = 3p^2 + 7^2 = 9p^2-49.
So (3p-7)(3p+7)= 9p^2 - 49.

You can check your answer (very important):
We'll use p=1.
(3-7)(3+7) = -40
9-49 = -40
The answer has been approved.

Hope this Helps! :)

The first two diamonds are filled in, can you figure out how the numbers are related when

balu736 [363]

Answer:

Step-by-step explanation:

Upper box in the diamond: Add the two numbers ⇒ (-2) + 3 = -1

Bottom box in the diamond : Multiply the two numbers ⇒ (-2) * 3 = -6

3) Upper box = (-6) + (-3) = (-9)

Bottom box = (-6) *(-3) = 18

4) Upper box = 1 +(-11) = -10

Bottom box = 1 *(-11) = -11

5) Upper box = 7+8 = 15

Bottom box = 7*8 = 56

Seventy cards are numbered 1 through 70 , one number per card. One card is randomly selected from the deck. What is the probabil

Vanyuwa [196]

Answer:

$Probability = \frac{2}{35}$

Step-by-step explanation:

Given

$Total = 70$

First, we need to list the multiples of 5

$M_5 = \{5,10,15,20,25,30,35,40,45,50,55,60,65,70\}$

Then, multiples of 3 $M_3 = \{3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69\}$

Next, is to list out the common elements in both

$M_3\ n\ M_5 = \{15,30,45,60\}$

$n(M_3\ n\ M_5) = 4$

The required probability is then calculated as thus:

$Probability = \frac{n(M_3\ n\ M_5)}{Total}$

$Probability = \frac{4}{70}$

$Probability = \frac{2}{35}$

Please solve for a need help

The two lines with arrows are parallel, which means angles A and B are supplementary.

So we have

A + B = 180º

(6x - 35)º + (3x + 53)º = 180º

(9x + 18)º = 180º

(9x)º = 162º

x = 18

This means angle A has measure

A = (6x - 35)º = 73º

A whole number is 6 more than 2 times another number. The sum of the two numbers is less than 50. This can be written in an ineq

alukav5142 [94]

Answer:

13, 14

Step-by-step explanation:

The parameters of the numbers are;

A whole number value = 2 × Another number + 6

The sum of the two numbers is less than 50

Given that the first number is equal to more than twice the second number, we have that the first number is the larger number, while the second number is the smaller number

Where 'x' represents the second number, we get;

x + 2·x + 6 < 50

Simplifying gives;

3·x + 6 < 50

x < (50 - 6)/3 = 14. $\overline 6$

x < 14. $\overline 6$

Therefore, the numbers for which the inequality holds true are numbers less than 14. $\overline 6$ . From the given option, the numbers are 13, and 14.
