Answer: 29.2cm
Step-by-step explanation: perimeter of parallelogram; 2(a + b) where a = base, b = altitude
a = 8cm
b = 6.6cm
Perimeter = 2(8 + 6.6) = 2(14.6)
Perimeter = 29.2cm
Answer:
a. 5 + x = -5 (Subtraction) 0.
b. -17 + x = 0 (Addition) 17.
c. 30 + x = 0 (Subtraction) -30.
d. x + (-27) = 0 (Addition) 27.
e. x + (-30) = 0 (Addition) 30.
Step-by-step explanation:
In this exercise, students are required to match each equation with its solution. (The corresponding operations must be presented at the end of this point
a. 5 + x = -5 (Subtraction) 0.
x = -5 - 5
x = 0
b. -17 + x = 0 (Addition) 17.
x = 0 + 17
x = 17
c. 30 + x = 0 (Subtraction) -30.
x = 0 - 30
x = -30
d. x + (-27) = 0 (Addition) 27.
x - 27 = 0
x = 0 + 27
x = 27
e. x + (-30) = 0 (Addition) 30.
x - 30 = 0
x = 0 + 30
x = 30
I think
J,BB,S
(I shortened name to letter)
1. false because they have the same slope and y-intercept so they have infinite number of solutions
2. true
