Answer:
Step-by-step explanation:
Given the expression 
, we are to find the value of with powers of 10.
From the equation:
cross multiply
divide both sides by 7.208
express x in powers of 10
Similarly given the equation 
From the equation:
cross multiply
divide both sides by 7.208
express x in powers of 10
For the equation 
From the equation:
cross multiply
divide both sides by 7.208
express x in powers of 10
Answer:
a^2+2ab+b^2
Step-by-step explanation:
FOIL method is First variables Outer variables Inner variables Last variables
(a+b)^2 rewritten is (a+b)(a+b)
F - a*a
O - a*b
I - a*b
L - b*b
a*a+a*b+a*b+b*b
simplify
a^2+2ab+b^2
(7-6)/6 leaves 1/6 multiplied by 100 is 100/6 which in percentage is 17%
Answer: Each triangle:40 cm²
Kite : 80cm²
Step-by-step explanation:
The area of a triangle is
1/2bh
The height of the triangle is
h=1/2(10)=5cm
and the base is 16 cm.
The area of each triangle is
= 1/2(16)(5)=40cm^2
2. The total area of the kite is 2 times the area of one triangle.
= 2*40=80cm^2
Answer: m = 0
Step-by-step explanation:
Slope (m) = y2 - y1/,x2 - x1 : meaning increase in y divided by increase in x . it can also be written as ∆y/∆x
y1= 1, y2 = 1, x1 = 7, x2 = -2
Substitute for those values in the equation above
m = 1 -1/-2 - 7
= 0/-9
Therefore,
m = 0
The slope of the line passing through those coordinates = 0
