Answer:
25
Step-by-step explanation:
I'll explain in detail for those of you that want to know.
You know that since angles B and C are congruent to each other that this triangle is an isosceles triangle. Therefore, sides AB and AC are congruent to each other because that is a property of an isosceles triangle.
To solve for x, place the expressions of sides AB and AC equal to each other and solve for the unknown variable.
4x + 1 = 2x + 23
You should get that x = 11.
Substitute x = 11 into the expression for side BC to solve for the length of that side.
f(11) = 3(11) - 8
f(11) = 25
Thus, length of side BC is 25 units.
Use this way of solving for all your future questions. It's really simple :)
Answer:
L: (15+6x) W: 2
L: (10+4x) W: 3
L: (5+2x) W: 6
Step-by-step explanation:
We don't have any numbers here to do calculations, so probably this is just an exercise in FACTORING. Also to practice that area is length times width.
The area given,
30 + 12x
can be factored several ways to be able to fill in the table.
This kind of factoring is like "un-distributive property" where a common factor can be factored out of the expression. Usually its helpful to factor out the greatest common factor (GCF) but in this case any common factor will do.
Also, unless there are more directions, either factor may be the length or the width.
2(15+6x)
3(10+4x)
6(5+2x)
