Please help!!!! Maths!!!!!
Answer:
x= 2 or x= -3
Step-by-step explanation:
Bring the equations together using a common denominator (x-5) (x+7)
x-29/(x-5) (x+7)= 1
Multiply both sides by (x-5) (x+7)
x- 29= (x-5) (x+7)
x- 29= (x-5) (x+7)= x^2 + 2x - 35
-x^2 - x + 6 = 0
-(x-2)(x+3)= 0
Multiply both sides by -1
(x-2)(x+3)= 0
Split it into two equations
x-2= 0 or x+3= 0
x= 2 or x= -3

Use the information to answer the following question.
A rectangular garden has a length that is 3 feet longer than its width. Let w represent the width of the garden in feet. The entire garden is surrounded by a 2-foot-wide cement walkway.
What does the algebraic expression (w + 4)(w + 7) represent in this context?
A. the perimeter of the walkway only
B. the area of the garden only
C. the perimeter of the garden only
D. the total area of the garden and walkway
Answer:
D. the total area of the garden and walkwayStep-by-step explanation:
Sides of the rectangular garden:
w and w + 3Add the width of the walkway, 2 feet from both sides, the total of 4 feet:
w + 4 and w + 7The product of the above is the area of the garden and the walkway
Correct option is D

Find the height of a triangle whose base is 5 inches and area is 12 square inches.
Answer:
Therefore, Height = 4.8 inches.
Step-by-step explanation:
Given : A triangle whose base is 5 inches and area is 12 square inches.
To find : Find the height of a triangle.
Solution : we have given
Triangle base = 5 inches.
Area = 12 square in.
We need to find height of the triangle.
Area = * base * height .
Plugging the values .
12 = * 5 * height .
On multiplying both sides by 2
24 = 5 * height .
On dividing both sides by 5.
Height = 4.8 inches.
Therefore, Height = 4.8 inches.

Step-by-step explanation:
\begin{aligned} &-x+4y=-9 \\\\ &y=-2x +6 \end{aligned} −x+4y=−9 y=−2x+6 Is (2,3)(2,3)left parenthesis, 2, comma, 3, right parenthesis a solution of the system?
Answer:
NO
Step-by-step explanation:
Given the system of equation
-x+4y = -9,... 1
y = -2x+6.... 2
To find the solution to the equation
Substitute equation 2 into 1
-x+4(-2x+6) = -9
-x-8x+24 = -9
-9x= -9-24
-9x = -33
x = 33/9
Find y
y = -2x+6
y = -2(33/9)+6
y = -66/9 + 6
y = -66+54/9
y = -12/9
y = -4/3
Hence (2,3) is not the solution to the system of equation

Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?
Answer:
We can make the paint amount equal by making sure the parameters have the same unit
Step-by-step explanation:
Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?
To solve the above question, we have the conversion rate:
We can make the paint amount equal by making sure the parameters have the same unit
Hence:
1 gallon (gal) = 3.785411784 kilogram (kg).
Billy had 5 gallons of paint.
1 gallon (gal) = 3.785411784 kilogram (kg).
5 gallons of paint = x
Cross Multiply
x = 5 × 3.785411784 kg
18.92705892 kilograms of paint
Approximately 18.93 Kilograms of paint
Therefore, Billy had 18.93 kg of paint and Bob had 4 kg of paint
