Hey there! I'm happy to help!

Let's use the distributive property to undo the parentheses. We multiply the number next to the parentheses by each number inside of the parentheses.

-7+3(-4e-3)

-7-12e-9

We combine like terms.

-16-12e

This means that Answer B is incorrect. Answer A could still be correct though as it could have equal value to -16-12e.

-4(3e+4)

We use distributive property.

-12e-16

We see that these have the same value, so the correct answer is A.

Have a wonderful day! :D

How do you solve: 21 11/12 plus 17 5/12

GarryVolchara [31]

The problem is $21 \frac{11}{12} + 17 \frac{5}{12}$

Add the whole numbers

$21 + 17 = 38$

Match up the fractions and make sure the denominators are the same (they are)

$\frac{11}{12} + \frac{5}{12}$ $= \frac{16}{12}$

Break down the fraction

$16$ ÷ $12 = 1 \frac{4}{12}$

Reduce-You need to find a common factor for both the numerator and denominator

$4$ ÷ $4$ $= 1$

$12$ ÷ $4 = 3$

Combine everything

$38 + 1\frac{1}{3} =39 \frac{1}{3}$

Answer: $39 \frac{1}{3}$

What quadrilateral always has 4 congruent angles and opposite that are congruent and paralle

nignag [31]

Another quadrilateral that you might see is called a rhombus. All four sides of a rhombus are congruent. Its properties include that each pair of opposite sides is parallel, also making it a parallelogram. In summary, all squares are rectangles, but not all rectangles are squares.
