A photograph is in the shape of a rectangle. It has a Iength of (x + 2) inches and a width of (x -2) inches. What is the area of the photograph?
Answer:
The area of the photograph is: [tex]A=x^2-4[/tex]
Step-by-step explanation:
Given
The length of rectangular photograph = [tex]l[/tex] = (x + 2) inches
The width of rectangular photograph = [tex]w[/tex] = (x - 2) inches
To determine
The area of the photograph
Important Tip:
Given that the photograph is in the shape of a rectangle. Thus, we can use the formula involving the area of a rectangle to determine the area of a photograph.
The Area of the photograph can be determined using the formula
[tex]A = wl[/tex]
where
[tex]A[/tex] is the area[tex]l[/tex] is the length[tex]w[/tex] is the widthnow substituting [tex]l = (x + 2)[/tex] and [tex]w = (x-2)[/tex] in the formula
[tex]A = wl[/tex]
[tex]A = (x-2) (x+2)[/tex]
Apply Difference of Two Squares Formula: [tex]\left(a-b\right)\left(a+b\right)=a^2-b^2[/tex]
[tex]A=x^2-2^2[/tex] ∵ [tex]a=x,\:b=2[/tex]
[tex]A=x^2-4[/tex] ∵ [tex]2^2=4[/tex]
Therefore, the area of the photograph is: [tex]A=x^2-4[/tex]

a softball team has a budget of 200$ for visors. An athletic director pays $90 for 12 sun visors for the softball team. is there enough money in the budget to buy 15 more sun visors?
Answer:
No
Step-by-step explanation:
So if the director paid $90 for 12 visors, we need to find how much one cost so 90/12 = 7.5
Then to find the cost of 15 visors, multiply 7.5 by 15 to get 112.5
now add 112.5 to 90 to see if it stays within the budget of $200, 112.5 + 90 = 202.5, so NO there is not enough money in the budget to buy 15 more sun visors.
Enter the unknown value that makes this statement true.

Maria correctly concluded that not enough information was provided to construct the requested proof. What extra information would allow Maria to contrast the proof? SA=TR. RS= ST. ASCT is similar to ASCA. SC=5/2BR
Answer:
Hello your question is incomplete attached below is the complete question
answer: RS = ST ( option b )
Step-by-step explanation:
First we consider Δ SCA and Δ TCB
∠ SCA = ∠ TCB , ∠CAS = ∠CBT = 90°
if we assume RS = ST then ΔSRT will be termed an Isosceles triangle with its legs : SR = ST. also vertex S bisects the base of the triangle.
Δ SBR ≅ ΔSBT from here we can deduce that ; BR = BT
From the assumptions what is actually missing to contrast the proof is : RS = ST

HELPPPP
Answer:
Tommie planted the most.
Tommie plants twice that amount, and Tommie plants more rows of pepper plants.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Alethea plants 3 rows of carrots for every 1 row of pepper plants.
And, Alethea plants 9 rows of carrots and Tommie plants twice that amount.
Here, Alethea plants 9 rows of carrots and Tommie plants twice that amount.
So, We get;
Tommie plants twice that amount, and Tommie plants more rows of pepper plants.

What is the measure of angle A?
Answer:
64 degrees
Step-by-step explanation:
A triangles angles always add up to 180. So add 58 + 58 to get 116. Now subtract 180 - 116 to find the measure of angle A. You get 64.
Hope it helps!
Step-by-step explanation:
58 +58 = 116
180-116 = 64
So angle 4 = 64
