Answer:
A.Yes B.Yes C.No D.Yes E.No F.No
Step-by-step explanation:
10% of 84 is 8.4 and 84-8.4=76.6 and anything between 76.6-84 could have been the estimate.
This is combining like terms:
-6x - 3x + 7x = -2x
Answer:
-2x + 4y + 8
Answer/Step-by-step explanation:
a. Diagonals of a rectangle are equal to each other. Therefore:
9x + 20 = 10x + 8
Collect like terms
9x - 10x = -20 + 8
-x = -12
Divide both sides by -1
x = 12
b. One of the properties of a rhombus is that, a diagonal of a rhombus bisects the angles of a rhombus. Therefore, this means that:
2x + 15 = 5x + 3
Collect like terms
2x - 5x = -15 + 3
-3x = -12
Divide both sides by -3
x = 4
Because the side has to be increased by 50%
you find half of 8, which is 4 and you add 8+4 because you add the increased amount
8+4=12
you then just find the area.... so 12x12= 144
