[tex]\frac{-5 + \sqrt{37} }{2}[/tex]
Note:Have no clue if its right
Answer:
see explanation
Step-by-step explanation:
The area (A) of the rectangle = length × breadth, that is
A = BC × CA
= (x + 3)(x + 2) ← expand using FOIL
= x² + 5x + 6
Given that A = 9 , then
x² + 5x + 6 = 9 ( subtract 6 from both sides )
x² + 5x = 3 ← as required

Answer:
3
Step-by-step explanation:
3 is the slope. Since it is y/x, then it is 9/3, which is simplified to 3/1.
Why?
You need two points to find slope I will use 5,19 and 2,10.
Slope is the difference of Y over the difference of x
19-10/5-2= 9/3 (simplify but divided each by 3)
3/1 so the slope is 3

Find the value of each variable in the parallelogram?
Answers
Answer:
Step-by-step explanation:
In parallelogram opposite angles are equal
6x = 66 {Divide both sides by 6}
x = 66/6
x = 11
20y - 46 = 13y + 10 {Add 46 to both sides}
20y - 46 + 46 = 13y + 10 + 46
20y = 13y + 56 {Subtract 13y from both sides}
20y - 13y = 13y-13y + 56
7y = 56 {Divide both sides by 7}
y = 56/7
y = 8

Answers
Answer: 33 1/3%
Step-by-step explanation:
Percentage increase of the shirt will be calculated as:
= Price Increase / Old price × 100%
Price Increase = $20 - $15 = $5
Old price = $15
Percent increase = Price Increase / Old price × 100%
= 5/15 × 100
= 1/3 × 100
= 33 1/3%
Answer:
it would be -25% because 15 is less than 20

¿Cuáles son las longitudes de un terreno rectangular, si se sabe que el ancho es dos veces más pequeño que el largo, y que su área es de 16, 200 m2? cuanto mide el ancho cuanto mide el largo
Answers
Answer:
El largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m
Step-by-step explanation:
Un rectángulo es un cuadrilátero con dos lados de igual longitud y dos lados de igual ancho que contiene cuatro ángulos rectos. Para encontrar el área de un rectángulo, debes multiplicar su longitud por su ancho. Es decir, el área del rectángulo es igual al largo por el ancho.
En este caso, sabes que el ancho es dos veces más pequeño que el largo. Entonces, siendo el largo x, el ancho tendrá un valor de x÷2.
Siendo el área del terreno rectangular 16,200 m², entonces
x*(x÷2)= 16,200 m²
Resolviendo:
x² ÷2= 16,200 m²
x²= 16,200*2 m²
x²= 32,400 m²
x= √32.400 m²
x= 180 m
Entonces, el largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m (180 m÷ 2)

A. 1/3
B. 1/2
C. 2/3
D. 3/2
Answers
Answer:
D. 3/2
Step-by-step explanation:
The scale factor is 1/2 from OP / NQ = 1/2. Because of that, MQ is equal to half of MP and QP is equal to half of MP. Therefore, QP = MQ = 2. The slope of MO is rise over run which is 6 / 4 or 3 / 2.

What is the measure of the vertex angle
Answers
Answer:
Vertex angle = 124°
Step-by-step explanation:
m<BAC = m<BCA (base angles of isosceles ∆ are congruent)
7x + 1 = 5x + 9
Collect like terms
7x - 5x = -1 + 9
2x = 8
divide both sides by 2
x = 4
Vertex angle = 180 - ((7x + 1) + (5x + 9)) (sum of triangle)
Plug in the value of x
Vertex angle = 180 - ((7*4 + 1) + (5*4 + 9))
Vertex angle = 180 - (29 + 29)
Vertex angle = 124°

You plan to go snowboarding this weekend in Pennsylvania. The resort charges $15.75 per hour in addition to a $25 deposit to rent a snowboard. Write and solve a linear equation to find the total cost to rent the snowboard from 8:30 a.m. to 12:30 p.m.
Answers
Answer:
$88 in total
Step-by-step explanation:
x = number of hours
y = total cost to rent the snowboard.
$25 is already guaranteed
25 + 15.75x = y
since it is 4 hours from 8:30 a.m. to 12:30 a.m. you put 4 into x.
25+15.75(4) = y
88 = y
