Answer:

16x^2-9

Step-by-step explanation:

\left(4x+3\right)\left(4x-3\right)

We´ll <u>Apply Difference Two Squares Formula:</u>

  • \left(a+b\right)\left(a-b\right)=a^2-b^2

\longmapsto \left(4x+3\right)\left(4x-3\right)

\longmapsto \left(4x\right)^2-3^2

<u>Apply exponent rule</u>:

  • \left(a\times \:b\right)^n=a^nb^n

\longmapsto 4^2x^2-3^2

\longmapsto 16x^2-9

Answer:

<h2>16x^2 - 9</h2>

Step-by-step explanation:

(<em>4x + 3)(4x - 3)</em>

<em>Using identity, (a + b) (a - b) = a^2 - b^2</em>

<em> </em>

<em>here</em><em>,</em><em> </em><em>a </em><em>=</em><em> </em><em>4x </em><em>+</em><em> </em><em>3</em><em> </em><em>and </em><em>b </em><em>=</em><em> </em><em>4x </em><em>-</em><em> </em><em>3</em><em>,</em>

<em>therefore, </em>

<em>=</em><em>></em><em> </em><em>(</em><em>4x) </em><em>^</em><em>2</em><em> </em><em>-</em><em> </em><em>(</em><em>3</em><em>)</em><em>^</em><em>2</em>

<em>=</em><em>></em><em> </em><em>16x^</em><em>2</em><em> </em><em>-</em><em> </em><em>9</em><em>.</em><em>.</em><em>.</em><em> </em><em>ans </em>

<h2><em>HOPE </em><em>IT </em><em>HELPS </em><em>U!</em><em>!</em><em>!</em><em>!</em></h2>

Jana and Tim both sell cleaning products to local housecleaning services. When Jana orders from the manufacturer of the products
evablogger [386]

Answer: Jana and Tim will only spend the same amount on purchase orders to their manufacturers when they each order products with a total purchase value of $100.

Step-by-step explanation:

Jana and Tim would only be incurring same amount when both total purchase is to a value of $100. This is so because by purchasing a goods worth same amount, they both end up incurring $15 dollar additional cost. Jana would spend $15 on shipping her goods, while Tim would pay $4 Handling fees and $11 dollar shipping fee which would also amount to $15. What this means is total spent for both Jana and Tim would amount to $115 each.

What coordinates are 7 units away from (2,−7)
AlekseyPX
One coordinate that is 7 units away from (2,-7) is (2,0). (2,0) is 7 units to the right of (2,-7)

Another coordinate is (9,-7). This one also works.

Question 1:
"Match" the letters
DE are the last two letters of BCDE
The last two letters of OPQR is QR
DE is congruent to QR

Question 2:
Blank 3: Reflexive property (shared side)
Blank 4: SSS congruence of triangles (We have 3 sets of congruent sides)

Question 3:
I'm guessing those two numbers are 7.
Since both are 7, AB and AE are congruent.
We know that all the other sides are congruent because it is given.
We also know that there is a congruent angle in each triangle.
Thus, the two triangles are congruent by SAS or SSS.
(Note: I couldn't prove this without the two "7"s because there is no such thing as SSA congruence)

Have an awesome day! :)

Tony misplaced 7 77 stamps from his collection. He knows that each stamp of his is worth $ 0 . 1 5 $0.15dollar sign, 0, point, 1
denis23 [38]
I take it that only 7 stamps are misplaced and that we are asked for the total value of the stamps including those which have been misplaced. 
If each is worth $0.15 then, the total worth of 7 stamps is $1.05. Then, we add this value to the value of his remaining stamps, $5.55, the answer would be $6.60.
