The answer to number 1 is C. Not sure how to get that, I just got it off line converting it with a website.
The answer to number 2 in B, also got that offline by converting it.
3.) Area of a circle:
Radius-16
16×16×3.14=803.84 rounded to the nearest number is 804.
Since this says ESTIMATED we look for the closest answer to 804.
The answer is C. 805 square meters. hope it helps!!!!!!!!!!!!!!!
To find which orders pairs fit into the inequality simply substitute the variables, x & y.
A:3*8+4*(-3)>=12, yep! 12>=12
B: 3*(-5)+4*2>=12, Nope! -7 is not >= 12
C:Yep! 20>=12
D: Yep! 17>=12
You multiply each side of the equation by 16 .
Answer:
- perfect square: 2, 5
- difference of squares: 1, 6
Step-by-step explanation:
If the two factors are identical, their product will be a perfect square.
If one of the factors is the difference of terms that are summed in the other factor, the product will be the difference of squares.
(a +b)(a -b) = a² -b² . . . . . matches the 1st and 6th choices
(a +b)(a +b) = (a +b)² . . . . matches the 2nd and 5th choices
Answer:
<h2><em>
2x-4</em></h2>
Step-by-step explanation:
Area of a rectangle = Length * Width
Given parameters
Area A = 8x2 – 10x – 12
Length of the rectangle = 4x+3
Required
Width of the rectangle.
Substituting the given parameters into the formula
8x2 – 10x – 12 = (4x+3)*width
width = 8x2 – 10x – 12
/4x+3
S
Factorizing the numerator
8x² – 10x – 12
= 2(4x²-5x-6)
= 2(4x²-8x+3x-6)
= 2(4x(x-2)+3(x-2))
= 2(4x+3)(x-2)
Width = 2(4x+3)(x-2)/4x+3
Width = 2(x-2)
Width = 2x-4
<em>Hence the width of the rectangle is 2x-4</em>
