<1 = <2
vertical angles (congruent)
<3 = <2
corresponding angles (congruent)
so that: <1 = <2 = <3 = 112 degree

Step-by-step explanation:
to find the area of rectangle is Lenght multiple with its Width
Answer:
9. -4x+19y-7
10. 7x+20
Step-by-step explanation:
9. To simplify this expression, simply combine like terms. Add all of the terms with the x variable together, then the terms with the y variable, then the constant terms. I will show this step by step, but usually you do not have to show this work. The order of the terms does not matter.
x variable terms: (4x-8x)+7y-2+6y+6y-5= -4x+7y-2+6y+6y-5
y variable terms: (7y+6y+6y)-4x-2-5=19y-4x-2-5
constant terms: (-2-5)-4x+19y=-4x+19y-7
10. To simplify this expression, expand all terms and then combine like terms. The first term can be expanded by multiplying each term in the parentheses by 2.
Expand terms: 2(5+3x)+(x+10)= 10+6x+x+10
Now, you can combine like terms as done on the last problem. Note that I got rid of the parentheses in the second term, as they did not matter (since there was no term in front of them).
x variable terms: (6x+x)+10+10=7x+10+10
constant terms: (10+10)+7x=7x+20
Answer:
To convert 3.041 into scientific notation, follow these steps:
Move the decimal 0 times to left in the number so that the resulting number, m = 3.041, is greater than or equal to 1 but less than 10
Since we moved the decimal to the left the exponent n is positive
n = 0
Write in the scientific notation form, m × 10n
= 3.041 × 10^0
Answer:
1/5
Step-by-step explanation:
There is an easy way I learned.
You can multiply 1/2 by 5/5
so you get 5/10 - 3/10
and the you subtract 5-3=2
2/10
simplify 1/5
