Answer:
10x-5
Step-by-step explanation:
Just multiply 5 by 2 and you get 10x and then multiply 5 by 1 which is 5 and use the minus symbol in the expression
so 10x-5
Answer:
Step-by-step explanation:
The volume of the prism is 252 cubic centimeters.
The volume of a rectangular prism is gotten by the formula:
V = l * w * h
where l = length
w = width
h = height
The height of the prism is 3 cm.
Let x be the width of the prism.
The length of the prism is 5 cm longer than the width.That is:
l = 5 + x
The volume of the prism is therefore:
V = (5 + x) * x * 3
This is the equation that models the volume of the tray in terms of x.
6/15 = 2/c...this is a proportion, so we must cross multiply
(6)(c) = (15)(2)
6c = 30..divide both sides by 6
c = 30/6
c = 5
and if u will notice...6/15 = 2/5...proportions are nothing but equivalent fractions.
Use dimensional analysis. 1 lb = 16 oz will be the conversion factor. 162 oz x (1 lb/16 oz) = 10.125 lb.
Step-by-step explanation:
9m²+8m-6-7m²-3m+3
first write like terms
9m²-7m2+8m-3m-6+3
second ad subtract the terms
2m²+5m-3
factorize
2m²-m+6m-3
m(2m-1)+3(2m--1)
(m+3)(2m-1)
m=-3. m=1/2
