Step-by-step explanation:
y = 90 degrees
Answer:
12. w - 13 = 15 w = 28
13. g + 58 = 93 g = 35
14. n - 7 = 9 n = 16
Step-by-step explanation:
only 12-14
30(x)<=145 and yes she would be able to make 4 bracelets because 30 x 4 = 120 and that is less than 145
Answer:
А.(x-6)(x2 + 6x + 36)
Step-by-step explanation:
Remember this formula for factorizing difference of 2 cubes:
a
3
−
b
3
=
(
a
−
b
)
(
a
2
+
a
b
+
b
2
)
In
x
3
−
216
,
a
3
=
x
3
b
3
=
216
a
=
3
√
x
3
=
x
b
=
3
√
216
=
6
Substitute
a
=
x
,
b
=
6
into the formula of
(
a
−
b
)
(
a
2
+
a
b
+
b
2
)
(
x
−
6
)
(
x
2
+ (
6
x
x
) +
6
2
)
=
(
x
−
6
)
(
x
2
+
6
x
+
36
)
(
x
−
6
)
(
x
2
+
6
x
+
36
)
is the factorized form of
x

−
216
For this case we have that the complete question is:
A spider ate 25% more bugs this month than last month. The spider ate 8 bugs last month. How many bugs did the spider eat this month?
So, we propose a rule of three:
8 bugs -----------> 100%
x -----------------------> 25%
Where the variable "x" represents the number of bugs equivalent to 25%.

Thus, 2 bugs represent 25%
If this month the spider ate 25% more, then it ate:

Answer:
This month, the spider ate 10 bugs
