Each dimension should be increased by four times so that the area is tripled and each dimension is equal in length.
What is a quadratic equation?
Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
In mathematics, a dimension is the length or width of an area, region, or space in one direction.
area = length × width
a = l × w
But, we want to triple than area;
3A = 3 (l × w)
3A = (k × l) (k × w)
k² = 3
k = √3
The new dimensions will be: 6√3 and 3√3
Increased Dimension: 6√3 - 6 and 3√3 - 3
let x is the amount of increase in each side:
(x + 6) (x + 3) = 3(18)
x² + 3x + 6x + 18 = 54
x² + 9x + 18 = 54
x² + 9x - 36 = 0
∵ x = 4
Hence, each dimension should be increased by four times so that the area is tripled and each dimension is equal in length.

Answer:
SA = 997.88 mm²
Step-by-step explanation:
height² = 20.5² - 13.3² = 420.25 - 176.89 = 243.36
height = √243.36 = 15.6
SA = (16 x 13.3) + (16 x 20.5) + (16 x 15.6) + (0.5 x 2 x 13.3 x 15.6)
SA = 212.8 + 328 + 249.6 + 207.48 = 997.88 mm²

Answer:
∠ADE = 59°
Step-by-step explanation:
4x + 15° + 13x + 7° = 90°
combine like terms:
17x + 22° = 90°
subtract 22° from both sides of the equation:
17x = 68°
divide both sides by 17:
x = 4
∠ADE = ∠CBD = 13(4) + 7 = 59°
Answer:
m∠ADE = 59°Step-by-step explanation:
m∠ADE is the same as m∠BCE, so
m∠ADE = (13x+7)°
In rectangle all angles are 90°, so:
4x + 15 + 13x + 7 = 90
17x + 22 = 90
17x = 90 - 22
17x = 68
x = 68÷17 = 4
Therefore:
m∠ADE = (13×4+7)° = 59°
One clay brick weighs 5.4 pounds. The brick is 4 inches long and 2 1/ 4 inches wide. If the clay weighs 0.02 pounds per cubic inch, what is the volume of the brick? Round your answer to the nearest integer.
Answer:
270 cubic inches
Step-by-step explanation:
Given :
Mass of the clay brick = 5.4 pounds
Density = 0.02 pounds per cubic inch
Length of the brick = 4 inch
Width = [tex]$2\frac{1}{4}$[/tex] inch
We know, density = mass / volume
Or Volume = mass / density
= 5.4 / 0.02
= 270 cubic inches
Therefore, the volume of the brick is 270 cubic inches.

Lola spends one-fourth of her monthly salary on her car payment. She spends $250 on her car payment. Write and solve an equation to determine Lola's monthly salary.
Answer:
$24 is her allowance. 1/3 of her allowance is $8. So you would multiply 8 times 3 because 8 is just 1/3 of her allowance and you want to find her total weekly allowance. 8 x 3 = 24

The 5th term in a geometric sequence is 120. The 7th term is 30. What are the possible values of the 6th term of the sequence.
Answer:
± 60
Step-by-step explanation:
aₙ = a₁ * rⁿ⁻¹
a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶ (1)
a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴ (2)
(1)/(2): 30/120 = 1/4 = r²
r = ± 1/2 or ± 0.5
a₁ = a₇/r⁶ = 30/0.5⁶ = 1920
a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60
The possible values of the 6th term of the sequence ± 60.
The 5th term in a geometric sequence is 120.
The 7th term is 30
We have to determine the 6th term of the sequence.
What is the formula for the nth term of the sequence?[tex]a_n = a* r^n[/tex]
a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶ ...... (1)
a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴ ... (2)
(1)/(2): 30/120 = 1/4 = r²
r = ± 1/2 or ± 0.5
a₁ = a₇/r⁶ = 30/0.5⁶ = 1920
a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60.
