Answer:
first box:6
second box: 1
Step-by-step explanation:
divide bothe 18b and 3y by 3 and you get those values.
Answer:
d
Step-by-step explanation:
Given y is directly proportional to x² then the equation relating them is
y = kx² ← k is the constant of proportion
To find k use the condition y =
when x =
, then
= k(
)² =
k ( multiply both sides by 8 )
1 = 2k ( divide both sides by 2 )
k = 
y =
x² ← equation of proportion
When y =
, then
=
x² ( multiply both sides by 2 )
9 = x² ( take the square root of both sides )
x = ±
= ± 3
with positive value x = 3 → d
Answer:
no it can't because
Step-by-step explanation:
coz the sum of any two angle should be greater than 3rd side
- 13 + 5 = 18 which is greater than 7
- 13 + 7 = 20 which is greater than 5
- 5 + 7 = 12 which is not greater than 13
so triangle cant be made
Answer:
9) u= -12
11) -18 over 2
