Which expression has least value when x=100?

Substitute 100 for x and solve:-




Since -99 is the smallest number here, the expression with the least value when x=100 is Option C -

Length of the rectangular photo = 22 inches
Width of the rectangular photo = 20 inches
Since, width of the frame outside the photo = x inches
Therefore, increase in length and width of the photo with frame = (x + x)
= 2x inches
Length of the photo with frame = (22 + 2x) inches
Width of the photo with frame = (20 + 2x) inches
Combined Area of the photo in the frame = Length × Width
= (22 + 2x)(20 + 2x)
= 22(20 + 2x) + 2x(20 + 2x)
= 440 + 44x + 40x + 4x²
= 4x² + 84x + 440
Therefore, polynomial representing the combined area of the photo in the frame will be (4x² + 84x + 440) square inches.
If width of the frame = 4 inches
Combined area of the photo = 4(4)² + 84(4) + 440
= <u><em>840 square inches</em></u>

☺ Hello mate__ ❤
◾◾here is your answer...
i think right question is this
(3x − 7y)^2
ok now start solving:-
(3x − 7y)^2
=> (3x − 7y) (3x − 7y)
=> 3x(3x- 7y) -7y(3x-7y)
=>. 3x.3x - 3x.7y-7y. 3x + 7y.7y
=> 9x^2 -27xy +27xy + 49y^2
=> 9x^2 + 49y^2
so your correct ans. is 9x2 + 49y2

I hope, this will help you.☺
Thank you______❤

Answer: 2(11+9)</h3>
Explanation:
22 = 2*11
18 = 2*9
We see that 2 is the GCF of 22 and 18. It's the largest shared factor.
Now use the distributive property to say the following
22 + 18
2*11 + 2*9
2(11+9)
To check the answer, multiply the outer 2 by each term inside to end up with 22+18 again.
