The length of a rectangle is 1 foot more than twice the width. The area is 55 square feet. Find the perimeter of the rectangle.
Answer:
5 ft and 11 ft
Step-by-step explanation:
l= 2w+1
A=lw= 55
w(2w+1)=55
2w²+w-55=0
integer solution of quadratic equation is:
w=5 ft
l= 2*5+1=11 ft
Answer:
32 feet
Step-by-step explanation:
Start by creating your 2 equations
l = 2w + 1
l * w = 55
Plug in l, the isolated variable
(1 + 2w)w = 55
w + 2w² = 55
2w² + w -55 = 0
( − 5 ) ( 2 + 1 1 ) = 0
w= 5
w= -11/2 <- the width can't be negative so this one is out
Plug width into the area formula to find length
l * 5 = 55
l = 11
Find the Perimeter
2(11) + 2(5)
22 + 10 = 32

What is (-3,0) be 90 degrees clockwise on a graph?
Answer:
(0, 3)
Step-by-step explanation:
Visualize this problem as being based on a circle of radius 3. (-3, 0) lies on this circle, straddling the x-axis.
Now if we rotate that radius (connecting the (0, 0) to (-3, 0) clockwise, the point (-3, 0) becomes the point (0, 3).

If each dimension of the rectangular prism is doubled, how will its total surface area change?
o The surface area doubles
o The surface area triples
o The surface area increases by a factor of four
o The surface area increases by a factor of eight
Answer:
The surface area increases by a factor of four.
Step-by-step explanation:
Answer: the surface are increases by a factor of 4
Step-by-step explanation:
The surface are without doubulo it it is- 56
and with it double is- 208
and 56 times 4 is 208
measures the rectangle doubled-
hieght- 4

What is the sum of the measures that represent the measures of each angle if m∠ABC=2x°, m∠CBD=3x°, and m∠EBD=4x°?
What is the measure of each angle?
Explain how an equation can be written to find m∠CBD.
Answer:
∠ABC= 40° ∠CBD=60° ∠EBD=80°
Step-by-step explanation:
Step 1: 2x+3x+4x=180
A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.
Step 2: 9x=180
Combine like terms
Step 3: x=20
Divide/ Isolate the variable
Step 4: 2(20)=40 3(20)=60 4(20)=80

Answer:
Mrs Washington class Mr Utley's class
Band: Chorus Band : Chorus
2 : 3 5 : 7
8 : 12 10 : 14
10 : 15 15 : 21
12 : 18 20 : 28
14 : 21 25 : 35
Mrs Washington has a greater ratio of band students to chorus students. I know my answer is correct because I compared the ratio of the band to chorus students where the Band was the same. When Band to chorus had 10:15 students for Washington's class, and Band to chorus had 10:14 in Utley's class. This means That Washington had more students.
Hope this helps!
