Let width of the rectangle be x.
Therefore ,Length= 3 + 2x
Area= 35
(3+2x)* x =35
3x + 2x^2 - 35 = 0
(2x-7)(x+5)
Therefore x=3.5
Length is 10 and Width is 3.5
Answer:
Area = length × width
90 = (3+2w) × w
w(2w + 3) = 90
2w² +3w = 90
2(w² +3/2w) = 90
Divide both sides by 2
2(w² +3/2w)/2 = 90/2
w² + 3/2w = 45
w² + 3/2w + (3/2•2)² = 45 + (3/2•2)²
w² + 3/2w + (3/4)² = 45 + (3/4)²
w² + 3/2w + 9/16 = 45 + 9/16
(w + 3/4)² = 729/16
Take the square root of both sides
√(w + 3/4)² = √729/16
w + 3/4 = 27/4
w + 3/4 -3/4 = ±27/4 - 3/4
w = 27/4 - 3/4 w = -27/4 - 3/4
w = 6m w = -7.5m
Area = length × width
90 = l × 6m
when x = 6m when x = -7.5 m
l = 90 m²/6m l = 90 m²/-7.5m
l = 15 m l = -12m
We cannot have negative dimension so
A = 90m²
l = 15m
w = 6m

-5/6(8+5b) = 75+5/3 b
Answer:
b = - 14
Step-by-step explanation:
Given
- [tex]\frac{5}{6}[/tex](8 + 5b) = 75 + [tex]\frac{5}{3}[/tex] b
Multiply through by 6 ( the LCM of 6 and 3 ) to clear the fractions
- 5(8 + 5b) = 450 + 10b ← distribute left side
- 40 - 25b = 450 + 10b ( subtract 10b from both sides )
- 40 - 35b = 450 ( add 40 to both sides )
- 35b = 490 ( divide both sides by - 35 )
b = - 14

what is 1/4 written as a percent?
Answer:
25%
Step-by-step explanation:
1/4 = 25/100
and that fraction as a decimal is .25, which is equal to 25%
The fraction number 1/4 in the form of a percentage will be 25%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The fraction number is 1/4. Then, convert the fraction number into a percentage, then we have
P = (1/4) x 100
P = 0.25 x 100
P = 25%
The fraction number 1/4 in the form of a percentage will be 25%.

Answer:
x = -8 + √114 ≈ 2.7 [nearest tenth]
y = 7
Step-by-step explanation:
Given that ∆CAB ≅ ∆CDB, you can use CPCTC [corresponding parts of congruent triangles are congruent] to evaluate the given lengths and angle measures, to show that the corresponding measures are the same for both triangles. Using the triangle sum theorem which states that all angles in a triangle must add up to 180°, you can find ∠ACB.
If ∠CAB = 70°, and ∠ABC = 60°,
∠ACB = 50° because ∠CAB + ∠ABC + ∠ACB = 180°.
∠CAB + ∠ABC + ∠ACB = 180° →
∠ACB = 180° – ∠CAB – ∠ABC
∠ACB = 180° – 70° – 60°
∠ACB = 50°
70° + 60° + 50° = 180°.
Remember, the order of the letters in the angle are very important because it corresponds to the parts of the angle that make up the vertex which is the middle letter, along with the first and last letters which are the endpoints.
Because ∆CAB ≅ ∆CDB,
∠ACB ≅ ∠DCB [CPCTC].
As indicated in the problem, ∠DCB = (x² + 16x)°.
Because ∠DCB ≅ ∠ACB = 50°,
(x² + 16x)° = 50°.
So this can be completed as a square by converting this into vertex form.
x² + 16x = (x + 8)² – 64.
Then, (x + 8)² – 64 = 50.
(x + 8)² – 64 + 64 = 50 + 64 →
(x + 8)² = 114 →
(x + 8) = ±√114 →
x = -8 ± √114 [one more step]
[The measure must be positive so the expression must be added]
x = -8 + √114.

Hey there!
The answer to your question is $58.24
First, we will find the clearance price by finding 70% of the original price, since 30% was taken off:
0.70 x 104
72.80
Then, we will find the price after the coupon by finding 80% off 72.80, since 20% was taken off:
0.80 x 72.80
58.24
