What is the product? (9 t minus 4)(negative 9 t minus 4) negative 81 t squared minus 16 negative 81 t squared + 16 negative 81 t
liraira [26]

The product is negative 81 t squared + 16 ⇒ 2nd answer

Step-by-step explanation:

The product of two binomials (ax + b)(cx + d), where a, b, c, and d are constant

  • Multiply (ax) by (cx) ⇒ 1st × 1st
  • Multiply (ax) by (d) and (b) by (cx) ⇒ ext-reams and nears
  • Add the two products ⇒ like terms
  • Multiply (b) by (d) ⇒ 2nd × 2nd

Let us find the product of (9 t - 4) and (-9 t - 4)

Multiply the 1st two terms

∵ (9 t)(-9 t) = -81 t²

Multiply the ext-reams

∵ (9 t)(-4) = -36 t

Multiply the nears

∵ (-4)(-9 t) = 36 t

Add the like terms

∵ -36 t + 36 t = 0

Multiply the 2nd two terms

∵ (-4)(-4) = 16

Write the answer

∴ (9 t - 4)(-9 t - 4) = -81 t² + 0 + 16

∴ (9 t - 4)(-9 t - 4) = -81 t² + 16

The product is  -81 t² + 16

The length of a picture frame is 2 inches more than the width. The perimeter of the frame is 36 inches. What is the length of th
ollegr [7]
Answer in one complete sentence:
____________________________________________
   "The length of the frame is ten (10) inches."
_____________________________________________
Explanation:
_____________________________________________
Perimeter = P = 36 in.
Length = L = 2 +2
Width = w .
_____________________________________________
These are the two equations for the system of equations:

P = 2L + 2w = 36 in.
L = 2 + w
_____________________________________________
Solve for "L" (length) of the frame.
______________________________________
In the equation:
______________________________________
P = 2L + 2w = 36.

{Note: standard knowledge; and/or look up: 
______________________________________
Formula for the Perimeter of a rectangle:  P = 2L + 2w} ;
_______________________________________
We are given:  P = 36 in.
 
Rewrite, substituting "2+w" for "L" ;

P = 2(2+w) + 2w = 36 ;
___________________________
Note:  2(2+w) = 2*2 + 2w = 4 + 2w .

Now, Rewrite the equation, substituting "(4 + 2w) for "2(2+w)" ;
__________________________________________________
P = (4 + 2w)  + 2w = 36 ;

P =  4 + 2w + 2w = 36 ;

Combine the "like terms" ;
____________________________________________
  + 2w + 2w = 4w ;
____________________________________________
   P = 4 + 4w = 36 ;  
____________________________________________
↔   4 + 4w = 36 ;
____________________________________________
Subtract "4" from EACH SIDE of the equation:
____________________________________________
  →  4 + 4w − 4 = 36 − 4 ;
____________________________________________
 to get:
____________________________________________
            →  4w  =  32 ;
____________________________________________
            → Divide EACH SIDE of the equation by "4" ; to isolate "w" on one side of the equation; and to solve for "w" ;  
____________________________________________
            →  4w / 4 = 32 / 4 ;

               →  w = 8 .
____________________________________________
Now, to solve for: "L" (the length).
____________________________________________
    Length:  L = 2 + w ; 

                 →  L = 2 + 8 = 10 inches.
____________________________________________
Answer in one complete sentence:
____________________________________________
   "The length of the frame is ten (10) inches."
