Answer:
see the procedure
Step-by-step explanation:
Identify
Let
x ---> the cost of the Xbox one at Walmart
Strategy
we know that
The cost of the Xbox one at Walmart multiplied by 2 plus $50 must be equal to $450
Set up
The algebraic expression that represent this situation is

Solve
solve for x


Check
substitute the value of x in the equation

----> is ok
Lets say the base is x and the height is y. The new base would be 1.2x and the new height would be 1.3y
Area of a triangle is base times height divided by 2:
1.2x*1.3y/2 = (1.2*1.3 + x*y)/2 = 1.56xy/2 = 0.78xy = 78% of xy
But a normal area would be 50% of xy
78% - 50% = 38%
ANSWER: 38% increase
Answer:
The first one 6 second 10
just got it right :)
Answer:
Perimeter = 100mm
Area = 60mm
Step-by-step explanation:
P= (3x2) + (2x2) =10cm
10mm to 1cm
10cm x 10 = 100mm
A= b x h
= 3 x 2
=6cm
6x10=60mm
