Answer:
A.A(n) expression is a mathematical relationship that uses one or more variables, numbers or operation symbols.
B.A(n) variable is a symbol that can be replaced by a number in a mathematical expression or equation.
C.A(n) equation is a mathematical sentence with an equal sign.
Answer:
1. P = 14cm; A = 10cm^2
2. P = 24cm; A = 12cm^2
3. P = 32cm; A = 63cm^2
4. P = 36cm; A = 80cm^2
5. P = 32cm; A = 60cm^2
6. P = 36cm; A = 81cm^2
7. P = 26cm: A = 30cm^2
8. P = 28cm; A = 49cm^2
9. P = 26cm: A = 42cm^2
Step-by-step explanation:
Formula to find perimeter for a rectangle:
length + width + length + width
l + w + l + w
Formula to find area for a rectangle:
length × width
l × w
1.
Perimeter (P): 5 + 2 + 5 + 2 = 14
Area (A): 5 × 2 = 10
2.
P: 6 + 2 + 6 + 2 = 24
A: 6 × 2 = 12
3.
P: 7 + 9 + 7 + 9 = 32
A: 7 × 9 = 63
4.
P: 10 + 8 + 10 + 8 = 36
A: 10 × 8 = 80
5.
P: 10 + 6 + 10 + 6 = 32
A: 10 × 6 = 60
6.
P: 9 + 9 + 9 + 9 = 36
A: 9 × 9 = 81
7.
P: 10 + 3 + 10 + 3 = 26
A: 10 × 3 = 30
8.
P: 7 + 7 + 7 + 7 = 28
A: 7 × 7 = 49
9.
P: 6 + 7 + 6 + 7 = 26
A: 6 × 7 = 42
Area will always have its units squared (cm^2) because the formula requires we multiply the numbers and therefore the units: cm × cm = cm^2
There is a method I use called the x method, I can’t show it to you but I will do my best to explain it
Basically, the factors of 5 and 7 must equal 36, so it’s kind of like cross multiplying
5 X 1
1 7
Five times seven equals 35
1 Times 1 equals 1
35 + 1 = 36
This is the answer:
(5x+1) (x+7)
Answer:
5.5 meters above start position.
Step-by-step explanation:
-Let X be the start position.
#Total distance below the start position is calculated as:
#Total distance above the start position X:
#Distance above/below start position is:
Hence, The vessel is 5.5 meters above the start position
