2x7+10^3+(10+6)I put it in a calculator and I got 1,030
but what I'm trying to figure out is how they got that.
Please explain clearly. Thank you!

Answer 1
Answer: Please, put away the calculator, pick up a pencil, and look at the problem.

Have you learned the "order of operations", or PEMDAS ?  It's the key
to this problem ... knowing what to do first, and what to leave for last.

You do things in this order:

P . . . parentheses
E . . . exponents (powers)
M . . . multiplication
D . . . division
A . . . addition
S . . . subtraction

                                              2 x 7   +   10³   +   (10 + 6)

Parentheses first:                2 x 7   +   10³   +        16

Powers next:                        2 x 7   +   1000   +     16 

Multiplication next:                  14     +   1000   +     16

Add that up and what do you get ?           I got  1030 .
Answer 2
Answer: PEMDAS- parenthesis, exponents, multiplication, division, addition, subtraction
The calculator will solve the equation in this order. There for the 10+6=16,
then the 10^3=1000, then the 2*7=14.
Added all together you get 1030

Figure ABCD has vertices A(−3, 2), B(2, 2), C(2, −4), and D(−3, −2). What is the area of figure ABCD?

Answers

Answer:

The area of the figure ABCD is 25\ units^(2)

Step-by-step explanation:

we have

A(-3, 2), B(2, 2), C(2, -4), D(-3, -2)

using a graphing tool

Plot the figure

see the attached figure

The figure is a trapezoid

The area of the trapezoid is equal to

A=(1)/(2)(AD+BC)AB

Find the distance between the points in the graph

we have

AD=4\ units

BC=6\ units

AB=5\ units

substitute

A=(1)/(2)(4+6)5=25\ units^(2)

Answer:

I believe 25 square units is the right answer.

By applying the basic proportionality theorem to triangle ABC, the length of DB is: A. 18 cm.

What is the basic proportionality theorem?

In Mathematics and Euclidean Geometry, the basic proportionality theorem states that when any of the two sides of a triangle is intersected by a straight line which is parallel to the third side of the triangle, then, the two sides that are intersected would be divided proportionally and in constant ratio.

By applying the basic proportionality theorem to triangle ABC, we have the following:

AD/DB = CE/EB

24/DB = 12/9

12DB = 216

DB = 216/12

DB = 18 cm.
