Answer:
12
Step-by-step explanation:
Since its a square, all the sides are the same.
(2x+8)4=20x+8
8x+32=20x+8
32-8=20x-8x
24=12x
x=2
2x+8= 2(2)+8= 12
Answer:
Step-by-step explanation:
The probability of rolling a 1 is 0.85; then the probability of rolling not 1 is
1 - 0.85 = 0.15
Each box that states rolling a 1 gets 0.85. Each box that states not rolling 1 gets 0.15.
second
first roll
roll
/ 0.85 1
1 0.85 /
\ 0.15 not 1
/ 0.85 1
not 1 0.15
\
\ 0.15 not 1
Answer:
s = 17 units
Step-by-step explanation:
In triangle ABD,
(AB)² + (BD)² = (AD)² (by Pythagoras Theorem)
=> 8² + 15² = s²
=> 64 + 225 = s²
=> s =
=> s = 17 units

Answer:
<h2>
176 cm²</h2>
Step-by-step explanation:
you have a square and 4 equal triangles, you find the area of all, and you sum.
square area = l²
8² = 64 cm²
triangle area = b*h/2
8 * 7 : 2 = 28 cm²
now we sum 1 square's area and 4 triangles' area.
64 + 28 + 28 + 28 + 28 = 176 cm²
or
64 + (28 * 4) = 176 cm²
