Answer:
32
Step-by-step explanation:
12 * (3 + 2²) / 2 - 10
12(3 + 4) / 2 - 10
12(7) / 2 - 10
84 / 2 - 10
42 - 10

Best of Luck!
Answer:
Step-by-step explanation:
4 because as shown below. An equilateral triangle has 3 lines of symmetry.
Answer:
14.50 cm
Step-by-step explanation:
Based on the midsegment theorem:
The midsegment connecting two sides of triangle is parallel to the third side of the triangle and the length of the midsegment line is half the length of the third side parallel to the midsegment.
From the diagram ;
QR // ZY
XY = 2 * 2.93 = 5.86
RS // XZ
XZ = 2 * 2.04 = 4.08
QS // XY
XY = 2 * 2.28 = 4.56
The perimeter :
(XY + XZ + XY)
5.86 + 4.08 + 4.56
= 14.50 m
Let D be dogs and C be cats
<em>dogs, d, is initially five less than twice the number of cats, c</em>
D + 5 = 2C
<em>If she decides to add three more of each, the ratio of cats to dogs will be</em>
D + 8 = 2C + 3
<em>Could Bea's Pet Shop initially have 15 cats and 20 dogs?</em>
Simply plug in the numbers
20 + 5 = 2(15)
This is clearly not true: 25 does not equal 30
