We need a picture of the lines
The rectangle is 7 x 4 so the area is 28 sq cm
The triangle has a base of 4 and a height of 3.
The formula is A = 1/2 * b*h
You have 2 triangles so:
2(1/2)*4*3= 12 sq cm
Add together:
28 + 12= 40 sq cm
Answer:
60x + 25 + 60y
Step-by-step explanation:
60 times x plus 60 times y plus 25
Answer:
1/18
Step-by-step explanation:
there are 12 marbles in the bag
P(choose red) = 2/12 = 1/6
P(choose blue after replacement) = 4/12 = 1/3
P(choose red, then blue with replacement) = (1/6)(1/3) = 1/18
That "equation" has an infinite number of "solutions", because
no matter what 'r' is, it's always a true statement.
The statement is equivalent to saying "I am I." or "You are you."
