w = 4
L = 7
Step-by-step explanation:
L = length of rectangle
w = width of rectangle
L = 3 + w
A = 28
A = L*w
=(3+w) * w
28 = 3w + w^2
w^2 + 3w - 28 = 0
w^2 + 7w - 4w - 28 = 0
w ( w + 7 ) - 4 ( w + 7 ) =0
( w - 4 ) ( w + 7 ) = 0
w = 4. and w = -7
take the postive value, w = 4
therefore L= 3+4 = 7
Answer:
Translation 4 units to the left., followed by
a translation 1 unit down.
Step-by-step explanation:
The parent function is y = x^2 which is a parabola that opens upwards and has a vertex at the point (0,0).
Y = (x + 4)^2 is the graph of x^2 translated 4 units to the left.
The - 1 translates the graph down 1 unit.
So the vertex of the new graph is at (-4, 1).
Answer:
What do you mean?
Step-by-step explanation:
Given:
The sum of 8 and B is greater than 22.
To find:
The inequality for the given statement and its solution.
Solution:
We know that, sum of two number is the addition of two numbers.
Sum of 8 and B = 8+B
It is given that, the sum of 8 and B is greater than 22.
Subtracting 8 from both sides, we get
Therefore, the required inequality for the given statement is and the solution is .
