Answer:

$^+_-\frac{\sqrt{7}}{2}.$

Step-by-step explanation:

$1.| \ sinx+cosx| =\sqrt{(sinx+cosx)^2}=\sqrt{sin^2x+2sinxcosx+cos^2x}=\sqrt{1+2sinxcosx};$

2) according to the item 1:

$sinx+cosx=^+_-\sqrt{1+2*\frac{3}{8}} =^+_-\sqrt{\frac{7}{4}}=^+_-\frac{\sqrt{7} }{2}.$

With or without tiles simplify and solve each equation below for x. record your work. a.3x-7=2

AfilCa [17]

Answer:

Step-by-step explanation:

Addition property of equality is adding the same number to both sides of an equation does not change the equation.

a+c=b+c

3x-7=2

add 7 both sides of an equation.

3x-7+7=2+7

simplify.

3x=9

divide by 3 both sides of an equation.

3x/3=9/3

simplify.

9/3=3

3*3=9

9/3=3

Hope this helps!

Thanks!

<h3>What is division?</h3>

The division is one of the four basic operations of arithmetic, which are the methods by which numbers are combined to form new numbers.
Addition, subtraction, and multiplication are the other operations.
At the most basic level, the division of two natural numbers is the process of calculating the number of times one number is contained within another.

Quotient:

A quotient is a quantity produced by the division of two numbers in arithmetic.
The quotient is widely used in mathematics and is also known as the integer part of a division, a fraction, or a ratio.

So, the quotient of 45/9 is 5 as:
