If
is the length and
the width, then
.
Since the area of the rectangle is
you have
Factoring the left hand side gives
Obviously the width can't be negative, so
. This means D is the answer, since it's the only option with this measure.
Answer:
(- 2, - 4 )
Step-by-step explanation:
Given the 2 equations
3x - 2y = 2 → (1)
5x - 5y = 10 → (2)
Multiply (1) by 5 and (2) by - 3, then add to eliminate x
15x - 10y = 10 → (3)
- 15x + 15y = - 30 → (4)
Add (3) and (4) term by term to eliminate x , that is
5y = - 20 ( divide both sides by 5 )
y = - 4
Substitute y = - 4 into either of the 2 equations and solve for x
Substituting into (1)
3x - 2(- 4) = 2
3x + 8 = 2 ( subtract 8 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
Solution is (- 2, - 4 )
Answer:
24
Step-by-step explanation:
simpley look up the lcm of 6 and 8 and youll get the answer... very simple
U multiply 1 x 17 x 2
The answer is 34 cm3(cubed)
The 3 behind cm is an exponent
Answer:
The graph of the rectangle missing in the question is shown in the figure attached.
Coordinates of the points are:
A(1,8)
B(4,5)
C(14,21)
D(17,18)
The area of the rectangle is AB*BD.
The length of a segment given two points (x1, y1) and (x2, y2) is computed as follows:
√[(y2 - y1)^2 + (x2 - x1)^2]
For segment AB:
√[(5 - 8)^2 + (4 - 1)^2] = √18
For segment BD:
√[(18 - 5)^2 + (17- 4)^2] = √338
Then, the area is:
AB*BD = (√18)*(√338) = √(18*338) = √6084 = 78
