Answer:
the perimeter is 960
Step-by-step explanation:
The computation of the perimeter is shown below;
If we assume
= (24 × 2) + (6 × 2)
= 48 + 12
= 60
And, the area is 16 times to that of original So
= 60 × 16
Hence, the perimeter is 960

Answer:
65 square units
Step-by-step explanation:
The area of a triangle is: height times base divided by two.
So the area of one of the triangles is 10 square units.
multiply this times 4 to get the total area of the triangles
then add the area of the square which is 5 times 5
25 plus 40 = 65 square units

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 .

Answer:
a. [tex]5 + (-3x) = -4[/tex]
b. [tex]5 + (-3x) = 4[/tex]
c. [tex]5 + (-3x) = 14[/tex]
Step-by-step explanation:
Given
[tex]5 + (-3x)[/tex]
Required
Evaluate
(a) x = 3
[tex]5 + (-3x) = 5 + (-3*3)[/tex]

Starbucks opened two new locations. Location A costed $800 to open but makes $100 a month. Location B costed $1200 to open but makes $200 a month. Determine how long it will take for the locations to have made the same amount after paying off their costs and how much that amount is.
Answer:
I think it is A that will take longer but im not 100 percent sure
Step-by-step explanation:
First write an equation:
Location A- 800+100x
Location B- 1200+200x
Then you need to plug numbers in for x

Answer:
ok
1st one x=245°
2nd one x= 250
Step-by-step explanation:
hope its correct
hope u find it helpful
Answer:
x = 245 and x = 20
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , then
sum = 180° × 3 = 540°
Sum the interior angles and equate to 540
25 + 112 + 100 + 58 + x = 540
295 + x = 540 ( subtract 295 from both sides )
x = 245
---------------------------------------------------------------
5x + 2 + 3x + 5 + 8x + 8 + 4x + 15 + 5x + 10 = 540
25x + 40 = 540 ( subtract 40 from both sides )
25x = 500 ( divide both sides by 25 )
x = 20

£399 is shared between ann,bill, chloe and dave. The ratio of the amount ann gets to bill gets is 2:9 chloe and dave get 2.5 times the amount ann gets.
Work out how much money bill gets
Answer:Bill gets £171
Step-by-step explanation:
Total Money shared = £399
The ratio of the amount Ann gets to bill gets is 2:9 Chloe and Dave get 2.5 times the amount Ann gets can be written as
Ann : Bill : Chloe : Dave
2 : 9 : 2.5 x Ann : 2.5 x Ann
Let the amount of money
Ann gets be x
so that Bill gets 4.5x
Chloe = 2.5x
Dave = 2.5x
So that the expression to calculate each amount gooten will be
x + 4.5x + 2.5x + 2.5x = 399
10.5x = 399
x = 399/10.5
x=38
Therefore, Ann gets = £38
Bill gets =4.5 x= 4.5 x £38 = £171
Chloe gets=2.5x =2.5 x £38 = £95
Dave gets=2.5x =2.5 x £38 = £95

A sports shop got a skateboard that cost them $80. In order to make a
profit, they decide to add a 37.5% markup. What is the retail price of the
skateboard?
The retail price of the skateboard = [tex] \color{hotpink}\boxed{\bold{\tt\bold{\$110}}}[/tex]
○=> Steps to derive correct answer :Given :
▪︎Cost price of a skateboard in a sports shop = $80
▪︎Percentage of markup in the price of the skateboard = 37.5%
Which means :
The retail price of the skateboard :
= Intial price of skateboard + 37.5% of it's initial price
[tex] = \tt80 + 37.5\% \: of \: 80[/tex]
[tex] =\tt 80 + \frac{37.5}{100} \times 80[/tex]
[tex] =\tt 80 + \frac{37.5 \times 80}{100} [/tex]
[tex] = \tt80 + \frac{3000}{100} [/tex]
[tex] =\tt 80 + 30[/tex]
[tex]\color{plum} = \tt\bold{\$110}[/tex]
Therefore, the retail price of the skateboard = $110
