Step-by-step explanation:
a square has sides 7.4cm long.
work out the area of the square.
Area of a square = Side x side
Area = 7.4 x 7.4
Area = 54.76 cm^2
Answer:
Area of the square = (Side of the square)²
Area of the square = (7.4 cm)² = 54.76 cm²
54.76 cm² is the right answer.i don’t understand this pls help me
Answer:
a) x = -9
b) p = (q - x)/3
Step-by-step explanation:
a) Substitute the values in to the equation
x = 3p + q
x = 3(-2) + -3
x = -6 + -3
x = -9
b) Make p the subject
x = 3p + q
(add 3p to both sides)
x + 3p = q
(subtract x on both sides)
3p = q - x
(divide on both sides)
p = (q - x)/3
Answer:
Given
x = 3p + qa)
p = -2, q = -3 ⇒ x = 3(-2) - 3 = -6 - 3 = -9b)
x = 3p + q3p = x - qp = (x - q)/3Find the equation of the line passing through the points (2, -1) and (-6, -5)
y = 2x - 5
y = -1/2 x
y = 1/2 x - 2
y = 1/2 x
Step 1: Find the slope
Point 1 = (2, -1)
Point 2 = (-6, -5)
m = (-5 - - 1) / (-6 - 2) = (-5 + 1) / (-6 - 2) = -4 / -8 = 1/2
m = 1/2
Step 2: Find the y-intercept
Slope-Intercept Form: y = mx + b
-m is the slope
-b is the y-intercept
---Plug in whichever point you want as well as the slope and solve for b
Point = (2, -1)
-1 = (1/2)(2) + b
-1 = 1 + b
b = -2
Step 3: Form the equation
Slope-Intercept Form: y = mx + b
m = 1/2
b = -2
y = 1/2x - 2

You sell tickets for admission to your school play and collect a
total of $156. Admission prices are $8 for adults and $4 for
children. you sold 24 tickets. How many adult tickets and how
many children tickets did you sell?
Adults tickets =
Children tickets =
Answer:
Adult tickets = 15
Children tickets = 9
Step-by-step explanation:
x = adult tickets
y = children tickets
8x + 4y = 156
x + y =24
Therefore,
x = 24 - y
y = 24 - x
Substitute,
8 (24 - y) + 4y = 156
192 - 8y + 4y = 156
-8y + 4y = 156 - 192
-4y = -36
y = 9
Therefore,
x + 9 = 24
x = 24 - 9
x = 15
Check your answers
8x + 4y = 156
8(15) + 4(9) = 156
120 + 36 = 156
156 = 156
knits hats for her family and friends. In the first week, she knits 4 hats. The next week, she has some help, and together, they knit four times as many hats. The following week, she has even more help, and they knit four times as many hats as the week before. The fourth week, Jillian, her friends, and family, knit four times as many hats as the third week.How many hats will they knit in the fourth week
Answer:

what is the answer and steps to solve problem-2(b - 4) = 12
Answer:
b= -2
Step-by-step explanation:
First, you distribute.
-2(b-4) = 12
-2b + 8 = 12
Then, you combine like terms.
There are no like terms.
So, Next, you subtract 8 from each side.
-2b + 8 = 12
-2b - 8 = 12 - 8
-2b = 4
Finally, you divide each side by -2
-2b / -2
4 / -2
Answer: b = -2
A rectangular garden 30m by 20m consists of a lawn 28m by 18m surrounded by a path. The path is to be made of concrete to a depth of 8cm. Cal the vol of cement required in m3.
The cement is delivered in bags each holding 1cubic metre. Cal the cost if the cement costs #600 per bag and the labour charges are #2000. The company states that the cost will be approximately #70 per square metre. Is this correct?
1) The required volume of cement is 7.68 m3.
2) The costs will be $ 6,800, and the company's statement about approximate costs is correct.
1) Given that a rectangular garden 30m by 20m consists of a lawn 28m by 18m surrounded by a path, and the path is to be made of concrete to a depth of 8cm, to calculate the volume of cement required in m3 the following calculation must be performed :
8cm = 0.08mPath area x 0.08 = Volume((30 x 20) - (28 x 18)) x 0.08 = X(600 - 504) x 0.8 = X96 x 0.08 = X7.68 = XTherefore, the required volume of cement is 7.68 m3.
2) Given that the cement is delivered in bags each holding 1 cubic meter, to calculate the cost if the cement costs $ 600 per bag and the labor charges are $ 2000 and determine, if the company states that the cost will be approximately $ 70 per square meter, if this statement is correct, the following calculations should be performed:
7.68 m3 = 8 bags (8 x 600) + 2000 = X 6800 = X
Therefore, the costs will be $ 6,800.
6800/96 = 70.833
Thus, the company's statement about approximate costs is correct.

Identify the range of the image that has been reflected over the y-axis given the domain is
(5, -3), (-2, -2), (-7, 2)
A. (5, 3), (-2, 2), (-7, -2)
B. (-5, -3), (2, -2,), (7, 2)
C. (-5, 3), (2, 2), (7, -2)
D. (5, 3), (-2, 2), (7, 2)
Range of the image whose domain is (5, -3), (-2, -2), (-7, 2) will be (-5, -3), (2, -2,), (7, 2) .
Given,
Domain of the image: (5, -3), (-2, -2), (-7, 2)
Now,
When the image is reflected over the y axis the coordinates of y axis changes but x coordinates remains the same.
So,
If domain of the image is (5, -3), (-2, -2), (-7, 2) then after reflection over y axis the range will be (-5, -3), (2, -2,), (7, 2) .
Therefore option B is correct.

Step-by-step explanation:
I missed the x >= 0.
therefore only positive x (and then renamed y) are possible for the reverse function
that is easy and quick.
y = x² + 2
y - 2 = x²
x = +sqrt(y - 2)
and after trading the variable names to a regular function definition we then have
y = +sqrt(x - 2)
