Answer: 16 inches.
Step-by-step explanation:
given data:
length of string A = 80 centimeters.
length of string B = 64 centimeters.
step 1
we solve for the Highest common denominator between them.
highest common denominator = 16.
what this represents is that no string would be cut more than 16inches so they can all have equal lengths at the end of cutting.
Answer:
If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
Add 15 and 9, then subtract that by 87. 63 should be your answer.
Answer:
8 feet
Step-by-step explanation:
Given data
Area= 64 square feet
Base= x feet
Height= x+8 feet
The expression for the area
A= 1/2b*h
substitute
64= 1/2*x*(x+8)
64= 1/2*x^2+8x
64= (x^2+8x)/2
cross multiply
64*2= x^2+8x
128= x^2+8x
rearrange
x^2+8x-128= 0
using the quadratic formula
a=1
b=8
c=-128
x= -b±√b^2-4ac/2a
x= -1±√8^2-4*1*-128/2*1
simplifying
x= 8
x=-16
Hence the height of the base is
h= 8 feet
