Answer:
k = 8
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 32 when x = 4, then
32 = 4k ( divide both sides by 4 )
8 = k
Answer:
36
Step-by-step explanation:
Square roots have a neat property: 
provided <em>a</em> and <em>b</em> are positive real numbers.
This property is what's behind simplifying square roots. You look for perfect square factors (4, 9, 16, 25, 36, ...) inside the square root sign.
Example: 
.
In this problem, both factors are perfect squares.
Answer:
4 shirts will cost about 25.32
Step-by-step explanation:
First, You can divide 19/3 and this will give you 6.33 repeating.

Answer:
C
Step-by-step explanation:
-2^4-5(5)+2(-2-3)^2
16-25+2(25)
16-25+50
41
The answer to this question is :
Part A
((3x+7)+(4x-2))x
(3x+7)+(4x-2): 7x+5
x(7x+5)
Part B
((3x+7)*(4x-2))x
x(12x²+22x-14)
12x³+22x²-14x
Part C
(3x+7)[4x-2(x)]
4x-2(x)
4x-2x
2x
2x(3x+7)
I hope this helps!!!!!!!
