Answer:
Length = 42.5 cm
Step-by-step explanation:
length of rectangle = 5 + 3w
So l = 5 + 3w where w = 12.5
Equation:
L = 5 + 3(12.5)
Solving the Equation:
L = 5 + 3(12.5)
L = 5 + 36 + 1.5
L = 42.5
Length: 42.5 cm

Answer:
x=-6
Step-by-step explanation:
Let x be the number
3x = x^2 -54
Subtract 3x
3x-3x = x^2 -3x-54
0 = x^2 -3x-54
Factor
What 2 numbers multiply to -54 and add to -3
-9*6 = -54
-9+6 = -3
0=(x-9) (x+6)
Using the zero product property
x-9=0 x+6=0
x=9 x=-6
The questions asks for the negative solution
x=-6
Yea it is.4\5 is greater than 2
Hello!
It is given information that this triangle is a right triangle, meaning that the Pythagorean Theorem can apply here.
We can set the length of a leg as an unknown variable 
.
Remember that it is the whole 
term being squared, meaning that it'll simplify to 
, not 
.
This means we can plug back in to find the sides.
The hypotenuse would be 
, or 4.2.
And the legs would be 1.4 and 4, respectively.
Hope this helps!
A) get rid of the fraction by finding the common denominator, 4. multiplying by 4 on both sides, I usually have it turned into a fraction, 4/1. The 2x=3/4, is now 8x=12/4 will be set as 8x=3. Divide 8, x=3/8.
B) The common denominator is 15. Multiply on both sides, -2/5 times 15/1 is -30/5 which becomes -6. And m/3 times 15/1 is 15m/3, 5m. divide the 5 and your answer is m=-5/6
