Answer:
A. by the SAS postulate.
Step-by-step explanation:
We have been two triangles. We are asked to determine the theorem by which both triangles could be proven congruent.
We can see that side DF of triangle DEF is equal to side AC of triangle ABC.
We can also see that side BC of triangle ABC is equal to side EF of triangle DEF.
The including angle between sides AC and BC of triangle ABC is equal to the including angle between sides DF and EF of triangle DEF.
Since both triangles have two sides and their included angles equal, therefore, triangle ABC is congruent to triangle DEF by SAS (Side-Angle-Side) congruence and option A is the correct choice.
Answer:
1) Solving the term using F.O.I.L we get
2) solving the term using F.O.I.L we get
3) Solving using square of binomial we get
4) Solving using square of binomial we get
Step-by-step explanation:
1) (3x + 5)(2x - 3). Solve using the F.O.I.L.
F.O.I.L stands for First, Outer Inner Last
We have
First: 3x(2x)
Outer: 3x(-3)
Inner: 5(2x)
Last: 5(-3)
Solving we get:
So, solving the term using F.O.I.L we get
2) (x + 2)(x – 13). Solve using the F.O.I.L.
F.O.I.L stands for First, Outer Inner Last
We have
First: x(x)
Outer: x(-13)
Inner: 2(x)
Last: 2(-13)
Solving we get:
So, solving the term using F.O.I.L we get
3) (x + 5)^2. Solve using the square of Binomial.
The square of binomial is:
Solving:
So, solving using square of binomial we get
4) (x -3)^2. Solve using the square of Binomial.
The square of binomial used is:
Solving:
So, solving using square of binomial we get
