Answer:
Step-by-step explanation:
let : x the length and y the width .... ( x > y and x ; y reals numbers )
the perimeter is : 2(x+y)
2(x+y) = 55...(1)
x/y = 7/4 ...(2)
by (2) : x = (7/4)y
subsct in (1) : 2( (7/4)y +y ) =55
(7/2)y +2y =55
multiply by 2
7y +4y = 110
11y = 110
y = 10
x = (7/4)(10)
x = 35/2
Answer:
27
Step-by-step explanation:
The answer is 27, because 9 x 3 = 27 and the smallest number that is the same is 27.
Hope this helps!
6.6766*10^4 is that number in scientific notation
Answer:
12.
Step-by-step explanation:
The number of zeros to an equation is the highest power of the polynomial.
A quadratic equation whose highest degree is 2, has two solutions.
The equation f(x) = 
will have 12 solutions (or zeroes) since the highest degree is 12.
Answer:
The value of w is 7.
Step-by-step explanation:
According to Pythagoras theorem,
Hypotenuse²=Perpendicular²+Base²
H²=P²+B²
Here,
Hypotenuse given=7√2
w=y
Perpendicular=Base=x
(7√2)²=x²+x²
49*2=2x²
(49*2)/2=x²
49=x²
√49=x
7=x
Perpendicular=x=7
