Answer:
A
Step-by-step explanation:
Isabella started with 10 points. We know that the first value of this will be 10. Then, she loses 20 points. This is represented with -20. Finally, she wins 45 points, which is shown by writing +45.
10 - 20 + 45

Have a nice day!
"coplanar"
Coplanar means they lie in the same plane.
Answer:
Step-by-step explanation:
Given:
The expression to expand is given as:
Let us expand the first two binomials of the given expression using FOIL method.
The FOIL method states that:
Now, let us multiply the result with the remaining binomial. Multiplying each term of the trinomial with each term of the binomial, we get:
Therefore, the equivalent expression after expanding is given as:
You posted a lot of questions. I'll do the first four problems to get you started.
============================
Problem 1
This sequence is arithmetic because we add the same amount (4) each time to get the next term. The first term is -2. The first five terms are: -2, 2, 6, 10, 14
============================
Problem 2
This sequence is geometric. We multiply each term by 1/4 to get the next term. We start with 8 as the first term. The first five terms are 8, 2, 1/2, 1/8, 1/32.
============================
Problem 3
Similar to problem 1. This time we're adding -19 to each term to get the next one. The starting term is -6. This sequence is arithmetic and the first five terms are -6, -25, -44, -63, -82
============================
Problem 4
Similar to problem 2. This sequence is geometric with common ratio 2/3. First term is 6. The first five terms are 6, 4, 8/3, 16/9, 32/27
Line AC has 7 spaces and line BE has 8
to know this you count from letter A to C which is 7. and then B to E which is 8
They ARE NOT CONGRUENT
