Ok so the perimeter is the sum of all four sides, in this case, 26cm. The sides are then x, x, x+5, and x+5. 26=x+x+x+5+x+5 OR 26=4x+10.
x+5=length
x=width
subtract ten from each side:
16=4x
divide both sides by four:
x=4
Now we know the width. The length is the width plus 5.
4+5=9
Length: 9cm
Width: 4cm
Answer:
m = 72.9 grams
Step-by-step explanation:
Given that,
The density of a cube, d = 2.7 g/mL
Side of the cube, l = 3 cm
The volume of the cube is :
Since, 1 mL = 1 cm³
Mass per unit volume is equal to the density of an object.
So, the mass of the cube is 72.9 grams.
just multiply 1800 by 8400 then divide by 4
Answer:
all u have to do is add up the denominator and numerators together because just because u see something as an add problem it's still more stuff to add 6+8=14 7+5=12 add up 14+12=26+blank=what
Step-by-step explanation:
hopefully this helped
