Find the value for x. Round your answer to the nearest hundredth. Area of the triangle = 8 ft^2
Answer:
x = 3.51
Step-by-step explanation:
Since, formula to determine the area f a triangle is,
Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
8 = [tex]\frac{1}{2}(x + 1)(3x - 7)[/tex]
16 = x(3x - 7) + 1(3x - 7)
16 = 3x² - 7x + 3x - 7
16 = 3x² - 4x - 7
0 = 3x² - 4x - 23
3x²- 4x - 23 = 0
By quadratic formula,
x = [tex]\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}[/tex]
x = [tex]\frac{4\pm \sqrt{(-4)^{2}-4(3)(-23)}}{2(3)}[/tex]
x = [tex]\frac{4\pm \sqrt{292}}{6}[/tex]
x = [tex]\frac{4\pm 17.09}{6}[/tex]
x = 3.51, -2.18
But the length of sides can't be negative.
Therefore, x = 3.51 will be the answer.

4x - 2 (x-2) = -4 + 5x -13
Answer:
x = 7
Step-by-step explanation:
Given
4x - 2(x - 2) = - 4 + 5x - 13 ← distribute left side and simplify
4x - 2x + 4 = 5x - 17
2x + 4 = 5x - 17 ( subtract 5x from both sides )
- 3x + 4 = - 17 ( subtract 4 from both sides )
- 3x = - 21 ( divide both sides by - 3 )
x = 7

Tenemos un rectángulo cuya área es (15n + 9nx) cm 2 y su base mide (3n) cm. Existe también un cuadrado con la misma altura del rectángulo, tal que si al área del cuadrado se le disminuye (9x 2 ) cm 2 , ésta medirá 1825 cm 2 . ¿Cuánto mide el área original del cuadrado?
Answer:
El área original del cuadrado es 34225 cm²
Step-by-step explanation:
Los parámetros dados son;
El área del rectángulo = (15·n + 9·n·x) cm²
La longitud de la base del rectángulo = (3·n) cm
La altura del cuadrado = La altura del rectángulo
El área original del cuadrado - 9·x² cm² = 1825 cm²
La altura del rectángulo = (El área del rectángulo) / (La longitud de la base del rectángulo)
∴ La altura del rectángulo = (15·n + 9·n·x) / (3·n) = 5 + 3·x
La altura del rectángulo = 5 + 3 · x = La altura del cuadrado
El área del cuadrado = Lado × Lado = Altura × Altura = (5 + 3·x) × (5 + 3·x)
∴ El área del cuadrado = (5 + 3·x) × (5 + 3·x) = 9·x² + 30·x + 25
Del área original del cuadrado - 9·x² cm² = 1825 cm², tenemos;
9·x² + 30·x + 25 - 9·x² = 1825
30·x + 25 = 1825
30·x = 1825 - 25 = 1800
x = 1800/30 = 60
x = 60
El área original del cuadrado - 9·x² cm² = 1825 cm²
El área original del cuadrado = 1825 cm² + 9·x² cm² = 1825 cm² + 9 × 60² cm² = 34225 cm²
El área original del cuadrado también se puede encontrar de la siguiente manera;
El área original del cuadrado = (5 + 3 × 60) × (5 + 3 × 60) = 34225 cm²
El área original del cuadrado = 34225 cm².

PLEASE HELP A college student has two different jobs. Her combined work schedules consist of no more than 48 hours in one week.
Which graph best represents the solution set for all possible combinations of the number of hours she worked at her first job, and y, the number of hours she worked at her
second job, in one week?
Answer
А
Answer:
B
Step-by-step explanation:
everything above 48 is shaded, she has no more than 48 hours
Only the first graph represents the given situation. The correct option is A.
Given:
A college student has two different jobs. Her combined work schedules consist of no more than 48 hours in one week.To find:
The graph that represents the solution set for all possible combinations of the number of hours she worked at her first job and the number of hours she worked at her second job, in one week.
Explanation:
Let [tex]x[/tex] be the number of hours she worked at her first job and [tex]y[/tex] be the number of hours she worked at her second job, in one week.
Her combined work schedules consist of less than or equal to 48 hours in one week. So,
[tex]x+y\leq 48[/tex]
The number of hours cannot be negative.
[tex]y\geq 0[/tex]
[tex]x\geq 0[/tex]
The related equation is [tex]x+y=48[/tex].
At [tex]x=0[/tex],
[tex]0+y=48[/tex]
[tex]y=48[/tex]
The y-intercept is [tex](0,48)[/tex].
At [tex]y=0[/tex],
[tex]x+0=48[/tex]
[tex]x=48[/tex]
The x-intercept is [tex](48,0)[/tex].
Check the inequality for [tex](0,0)[/tex].
[tex]0+0\leq 48[/tex]
[tex]0\leq 48[/tex]
The above statement is true. It means [tex](0,0)[/tex] is included in the shaded region.
Therefore, the correct option is A.

Eli needs pieces of ribbon cut into strips that are 2 1/2 feet long. The roll of ribbon is 7 1/2 feet long. Which expression could be one of the steps in determining how many strips can be cut?
Hi there! 2 ½ is equivalent to 2.5 and 7 ½ is equivalent to 7.5. An expression that can be used to find out how many strips can be cut is this:
2.5x = 7.5
This is because the length of the ribbon needed to be cut is 2.5 ft long and we are looking for how many of that length could be cut out of a roll of ribbon that is 7.5ft long. All you have to do for this is divide both sides by 2.5 to isolate the variable. 7.5/2.5 is 3. x = 3. Eli can cut 3 strips of 2½ ft long ribbon.
