Solve the expression 2(5x5)+3 x 7

If you meant , then

Step-by-step explanation:

We use the order of operations, which state to use operations in this order:

Parentheses(apply the following steps to the things in the parentheses), Exponents, Multiplication and Division(from left to right), Addition and Subtraction(from left to right)

We then apply that to this expression, to get

The * stands for multiplication.

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
