Essentially, the figure FEHG got scaled by a factor of 1.5, and turned into BADC
So 2.4 times 1.5 is 3.6
3.6 = x
Hope this helps! #teamtrees #WAP (Water And Plant)
Answer:
The x would be 3.6
Step-by-step explanation:
If you see the relation or ration between the ABCD triangle and the EFGH then we can see that the side 2 is multiplied by 1.5 to get to 3. so you do the same thing to 2.4 and multiple that by 1.5 and 3.6.

a. The equation will be of the form x(x+2) = 80.
b. The two numbers are 8 and 10.
What is an integer ?An integer is a number which has no decimal value.
According to the given question we have to write an equation representing the fact the product of two consecutive even integers is 80.
Let us represent the smaller integer x and the greater integer by (x+2).
As even numbers comes after every 2 digits.
∴ x(x+2) = 80
x² + 2x = 80
x² + 2x - 80 = 0
x² + 10x - 8x - 80 = 0
x(x+10) - 8(x+10) = 0
(x+10) = 0 OR (x-8) = 0
x = -10 OR x = 8. ( x = 8 is the valid option as it satisfies the given equation)
The two integers are 8 and 10.

A grocery store sells a bag of 7 oranges for $2.80. What is the unit cost?
Answers
Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

Answers
Answer:
3a² + 3b² - 20ab
Step-by-step explanation:
Sum of 12ab-10b²-18a² and 9ab+12b²+14a²
12ab - 10b² - 18a² + 9ab + 12b² + 14a²
= 14a² - 18a² + 12b² - 10b² + 12ab + 9ab
= -4a² + 2b² + 21ab
Sum of ab + 2b² and 3b²- a²
= ab + 2b² + 3b²- a²
= -a² + 2b² + 3b² + ab
= -a² + 5b² + ab
Subtract
-a² + 5b² + ab - (-4a² + 2b² + 21ab
)
= -a² + 5b² + ab + 4a² - 2b² - 21ab
= 3a² + 3b² - 20ab

She made 87% of her shots
Player C had the highest conversion percentage and is thus the winner
The sum of the interior angles of each polygon is 360°. In the diagram ABCD=HGEF find the values of x and y look at photo below
Answers
Answer:
x = 3
y = 60°
Step-by-step explanation:
The given parameters of the figures are;
The sum of the interior angles of each polygon (quadrilaterals) = 360°
Quadrilateral ABCD = Quadrilateral HGEF
∴ ABCD ≅ HGEF
Therefore;
Segment AB ≅ Segment HG, by Corresponding Sides of congruent polygons are congruent
∴ The length of segment AB = 3 ft. = The length of segment HG = x ft.
∴ 3 ft. = x ft.
x = 3
Similarly, we have;
∠A + ∠B + ∠C + ∠D = 360° Given
∠B = 100°, and ∠D = 70° Given
∴ ∠A + ∠C = 360° - (∠B + ∠D) = 360° - (100° + 70°) = 190°
∠A + ∠C = 190°
∠A ≅ ∠G and ∠C ≅ ∠E Corresponding angles of congruent polygons are congruent
∴ ∠A = ∠G and ∠C = ∠E By definition of congruency
∴ ∠A + ∠C = ∠G + ∠E = 190° by transitive property
∠G = (2·y + 2)°, and ∠E = (y + 8)° Given
∴ ∠G + ∠E = (2·y + 2)° + (y + 8)° = (3·y + 10)° = 190°
3·y = 190° - 10° = 180°
y = 180°/3 = 60°
y = 60°
The value of x and y are 3 feet and 72 degrees respectively
Angle in a quadrilateral.From the given quadrilaterals, the sum of adjacent angles is 180 degrees.
Hence from figure;
m<E + m<F = 180m<B = m<F = 100y + 8 + 100 = 180
y + 108 = 180
y = 180 - 108
y = 72degrees
Similarly;
m<D = mG = 70 degrees.
AB = GH = 3 feet
Hence the value of x and y are 3 feet and 72 degrees respectively

Answers
Answer:-15
Step-by-step explanation:
The value of x in the given expression (3x + 17) (8x - 46) is -17/3 or 23/4
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given is an expression, (3x + 17)(8x - 46), we need to find the value of x,
(3x + 17)(8x - 46)
To find the value of x, equate the expression to 0,
(3x + 17)(8x - 46) = 0
3x+17 = 0
x = -17/3
or
8x-46 = 0
8x = 46
x = 23/4
Hence, the value of x is -17/3 or 23/4

The unit rate for peaches is $2.00 per pound. The unit rate for grapes is $2.50 per
pound. If you had $10 to spend, would you be able to buy a greater weight of
peaches or of grapes? Explain your answer.
Answers
Answer: A greater weight of peaches will be bought
Step-by-step explanation:
The unit rate for peaches = $2.00 per pound.
The unit rate for grapes = $2.50 per
pound.
Amount to spend = $10
Weight of peaches to buy with $10 = $10 / $2.00
= 5 pounds
Weight of grapes to buy with $10 = $10 / $2.50
= 4 pounds
Therefore, a greater weight of peaches will be bought as 5 pounds will be bought instead of 4 pounds for grape.
