The answer is D.
To get an area of any 4 sided object (like you text book) , we multiply the length and the width.
All the other answers don't multiply only 2 numbers together, so we know it must be D)
Answer:
<u>L = 12 inches and W = 8 inches</u>
<u>Area = 96 in^2</u>
Step-by-step explanation:
Perimeter(P) = 2(width) + 2(length)
Let W = width and L = length
P = 2W + 2L
L = 2W - 4
Substitute: P = 2W + 2(2W - 4)
P = 6W - 8
P = 40 inches
40 = 6W - 8
6W = 48
W = 8
L = 2W - 4
L = 2(8) - 4
L = 12
<u>L = 12 inches and W = 8 inches</u>
<u>===============================</u>
Check to see if this works:
P = 2W + 2L
P = 2(12) + 2(8)
P = 24 + 16
P = 40 inches <u>YES</u>
<u>========</u>
Area = WxL
Area = (12)*(8)
<u>Area = 96 in^2</u>
Answer:
Step-by-step explanation:
Each equation is in vertex form, so you can easily determine the number of real roots. The leading coefficient tells you whether the parabola opens upward (positive) or downward (negative).
y = a(x -h)^2 +k
has leading coefficient "a" and vertex (h, k).
__
<u>f(x) = 1/3(x +5)^2 +7</u>
vertex: (-5, 7), opens downward
The vertex is above the x-axis, so there are two real roots.
__
<u>f(x) = -5(x -3)^2</u>
vertex: (3, 0), opens downward
The vertex is on the x-axis, so there is one real root.
Ok so 9(46) means
9*46
So 9*46 would be ur 1st way and ur 2nd would be
46*9
Check:-
9*46=414
46*9=414
Ans
9*46
46*9
Hope I helped:P
