Answer:
Width = 16 m
Length = 4 m
Step-by-step explanation:
The area of rectangular is 64m² the length of the pool is 12 m less that the width . The situation can be represented by the equation x
Area of a rectangle = Length × Width
L = W - 12
Hence:
64 = (W - 12) × W
64 = W² - 12W
W² - 12W - 64 = 0
Factor using
(W + 4)(W - 16) = 0
Width = 16m
Length = W - 12
Length = 16 m - 12 m
= 4 m

You guys are Smart, Answer me this. But I need It fast-
Answer:
E = 58
F = 32
G = 90
Step-by-step explanation:
3x + 31 + 5x -13 + 90 = 180
3x + 31 + 5x -13 = 90
8x = 90 - 31 + 13
8x = 72
x = 72 / 8
x = 9
E = 3(9) + 31 = 27+31 = 58
F = 5(9)-13 = 45 - 13 = 32
G = 90

Simplify the expression using the order of operations. The nature park has a pride of 4 lions and 8 cubs. The adults eat 7 pounds of meat each day and the cubs eat 4 pounds. Simplify 4 × 7 + 8 × 4 to find the amount of meat consumed each day by the lions. The lions consume pounds of meat each day.
Answer:
60 pounds of meat
Step-by-step explanation:
Number of lions = 4
Pounds of meat consumed = 7 pounds each
Number of cubs = 8
Pounds e meat consumed = 4 pounds each
Amount of meat consumed each day by the lions = 4 × 7 + 8 × 4
Multiply first
= 28 + 32
= 60 pounds of meat
The lions consume 60 pounds of meat each day.
What is 3 divided by 6 Keep change flip?
Step-by-step explanation:

Which equation best represents the graph?
Answer:
The third one
Step-by-step explanation:
The graphs in the reversed shape of a cup are the graphs of quadratic equations whose coefficient of
x^2 is negative.
So, the answer must be either the first or the third.
It can be seen that when x= -4, y becomes 5.
Substituting the value of x, the third equation gives the value 5.
So, the answer is the third one.

Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26 By what percentage has Rebecca's car insurance been reduced?
Answer:
Step-by-step explanation:
Rebecca's car insurance been reduced by 18%
What is percentage?A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.
Given that, Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26.
Percentage decrease = (Final value - initial value) / initial value × 100
Final value = £1675.26
Initial value = £2043
Percentage decrease = (2043 - 1675.26) / 2043 × 100
= 367.74 / 2043 × 100
= 0.18 × 100
= 18 %
Hence, Rebecca's car insurance been reduced by 18%

Carran is building a fence around his rectangular yard. The fence will cover the front and the 2 sides of the yard. The
front of the yard is 4 feet more than twice the length of one side of the yard. The sides of the yard are the same length. If
the perimeter of the yard is 80 feet, what are the dimensions of the fence?
9514 1404 393
Answer:
sides: 12 feetfront: 28 feetStep-by-step explanation:
Let x represent the length of one side of the yard. Then the width of the yard is 2x+4, and the perimeter is ...
P = 2(L +W) . . . . . . . . . . formula for perimeter of a rectangle
80 = 2(x + (2x+4)) . . . . . with values from the problem filled in
40 = 3x +4 . . . . . . . . divide by 2, collect terms
36 = 3x . . . . . . . . . subtract 4
12 = x . . . . . . . . . divide by 3. This is the length of the side fence.
2x +4 = 2(12) +4 = 28
The fence is 12 feet on the sides and 28 feet on the front. (Its total length is 52 feet.)

Use Substitution to solve the following System of Equations.
y=-22 - 4
y = 4x + 2
Oh
Answer:
X=4
Y=18
I think
Answer:
(- 1, - 2 )
Step-by-step explanation:
Given the 2 equations
y = - 2x - 4 → (1)
y = 4x + 2 → (2)
Substitute y = 4x + 2 into (1)
4x + 2 = - 2x - 4 ( add 2x to both sides )
6x + 2 = - 4 ( subtract 2 from both sides )
6x = - 6 ( divide both sides by 6 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (2)
y = 4(- 1) + 2 = - 4 + 2 = - 2
solution is (- 1, - 2 )
The square of a number x is 16 more than six times the number
Form an equation in x and solve it.
Answer:
x= 8
Step-by-step explanation:
x^2 = 6x+16
TAKE RHS OVER TO LHS TO EQUATE IT TO 0
x^2 - 6x - 16 = 0
FACTORISE
(x-8)(x+2) =0
Therefore
x-8= 0 or x+2= 0
x= 8 or x= - 2
Sub and see which works
8^2 = 6(8) + 16
64= 64
-2^2 = 6(-2) + 16
-4= 4
So the answer must be
x= 8

what is the least common denominator of 9/10 and 1/4
Answer:
Step-by-step explanation:
Solution:
Rewriting input as fractions if necessary:
9/10, 1/4
For the denominators (10, 4) the least common multiple (LCM) is 20.
LCM(10, 4)
Therefore, the least common denominator (LCD) is 20.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
9/10 = 9/10 × 2/2 = 18/20
1/4 = 1/4 × 5/5 = 5/20
