Answer:
length = 60 cm
Step-by-step explanation:
ratio of width : length = 3 : 4 = 3x : 4x
perimeter = (2 × width ) + (2 × length) = 6x +8x = 14x
now perimeter = 210, hence
14x = 210 ( divide both sides by 14 )
x = 15
hence length = 4 × 15 = 60 cm
Given:
The given statement are:
a. Eight less than the product of seven and x.
b. The sum of six and the product of three and d.
To find:
The expression for the given statements.
Solution:
a.
Product of 7 and x is 7×x = 7x.
Eight less than the product of seven and x is 7x - 8.
Therefore, the required expression for the statement "Eight less than the product of seven and x" is 7x-8.
b.
Product of 3 and d is 3×d = 3d.
The sum of six and the product of three and d is 6+3d.
Therefore, the required expression for the statement "The sum of six and the product of three and d" is 6+3d.
4x^2 - 64
= 4(x + 4) (x - 4)
Answer:
X = 2
Explaination:
To find x, we can solve the rational equation by combining expressions, and isolating the variable x.
6/x=9/3
So, Y is 3 when X is 9.
so, it should go like this:
9/3, 6/2, 3/1
that's how you find it.
