The length of a rectangular lower garden is 5 feet more than its width. If the area of the garden is 150 square feet. Create an equation and solve to find the dimensions of the rectangle. You must use the Factoring method, Quadratic Formula, or Completing the Square to solve.
Pls help, I'll give brainliest
D.
If you plotted the points you would get a 16 by 4 triangle
base x height / 2 = area
16 x 4 / 2 = 32
area of rectangle is length x width
8 x 2 = 16
32 is two times the area of 16
Hope this helps

Hello, The answer is C
Step-by-step explanation:
Have a Great Day!
Part 1) [tex]54\ ft^{2}[/tex]
Part 2) The surface area is [tex]SA=(7\frac{\sqrt{95}}{2}+171)\ ft^{2}[/tex] or [tex]SA=205.11\ ft^{2}[/tex]
Part 3) [tex]V=63\frac{\sqrt{95}}{4}\ ft^{3}[/tex] or [tex]V=153.51\ ft^{3}[/tex]
Step-by-step explanation:
Part 1) How much material does he need to cover the one rectangular side of the tent with the rip?
we know that
The area of a rectangle is equal to
[tex]A=LW[/tex]
we have
[tex]L=9\ ft[/tex]
[tex]W=6\ ft[/tex]
substitute the values
[tex]A=(9)(6)=54\ ft^{2}[/tex]
Part 2) If David’s dad wanted to re-cover the whole tent including the bottom, how much material would he need?
we know that
The surface area of a triangular prism (the tent) is equal to
[tex]SA=2B+PL[/tex]
where
B is the area of the triangular face
P is the perimeter of the triangular face
L is the length of the triangular prism
Find the area of the triangular face B
Note The height of the triangle cannot be equal to 6 ft. The height of a right triangle cannot be equal to the hypotenuse. The height must be calculated by applying Pythagoras theorem
[tex]B=\frac{1}{2}bh[/tex]
we have
[tex]b=7\ ft[/tex]
Find the height applying the Pythagoras Theorem
substitute the values
[tex]h^{2}=6^{2}-(7/2)^{2}[/tex]
[tex]h^{2}=95/4[/tex]
[tex]h=\frac{\sqrt{95}}{2}\ ft[/tex]
substitute
[tex]B=\frac{1}{2}(7)(\frac{\sqrt{95}}{2})[/tex]
[tex]B=7\frac{\sqrt{95}}{4}\ ft^{2}[/tex]
Fin the perimeter of the triangular base P
[tex]P=6+6+7=19\ ft[/tex]
Find the surface area SA
[tex]SA=2(7\frac{\sqrt{95}}{4})+(19)(9)[/tex]
[tex]SA=(7\frac{\sqrt{95}}{2}+171)\ ft^{2}[/tex] -----> exact value
or
[tex]SA=205.11\ ft^{2}[/tex] -----> approximate value
Part 3) What is the volume of the tent?
we know that
The volume of the tent is equal to
[tex]V=BL[/tex]
where
B is the area of the triangular face
L is the length of the tent
we have
[tex]B=7\frac{\sqrt{95}}{4}\ ft^{2}[/tex]
[tex]L=9\ ft[/tex]
substitute
[tex]V=(7\frac{\sqrt{95}}{4})(9)[/tex]
[tex]V=63\frac{\sqrt{95}}{4}\ ft^{3}[/tex] -----> exact value
or
[tex]V=153.51\ ft^{3}[/tex] -----> approximate value
3. f(-6) = 12+1 =13
f(-2) = 4+1 = 5
f(0) =1
Range {1,5,13}
4. f(-2) = (-2)^3+1 =-7
f(-1) = (-1)^2 +1 =0
f(3) = (3)^3 +1 = 28
Range = {-7,0,28}
5.the sequence is arithmetic
d= -11+19 = 8
an = a1 + d(n-1)
an = -19 +8(n-1)
6.l =w+5
a =l*w
a(w) =(w+5) * w
a(w)= w^2 +5w
f(w) = w^2 +5w
f(8) = 8^2 +5(8)
f(8) = 64 +40
f(8) =104 in^2
3x+12
Step-by-step explanation:
3 times x = 3x
3 x 4 = 12
So then,
3x+12 is the answer!!
