Answer:
The answer is angle 7, 3, and 2
Step-by-step explanation:
Angle 7 is vertical, angle 3 is alternate exterior, and angle 2 is corresponding.
B is the correct answer.
We are adding the border of x thickness to all 4 sides of the table. This makes the new width of the table 36+x+x = 36+2x and the new length of the table 72+x+x=72+2x. To find the area, we multiply the length and width:
(36+2x)(72+2x) = 3006
Multiplying the binomials, we get:
36*72 + 36*2x + 2x*72 + 2x*2x = 3006
2592 + 72x + 144x + 4x² = 3006
Combining like terms gets us
2592 + 216x + 4x² = 3006
Subtract 3006 from both sides:
2592 + 216x + 4x² - 3006 = 3006 - 3006
-414 + 216x + 4x² = 0
Writing in standard form we have
4x²+216x-414=0
Answer:
Step-by-step explanation:
Here, we have to find the sum of 2 fractions:
1st fraction: 
2nd fraction: 
Considering the denominator of 1st fraction:
Using factorization method:
can be written as 
.
Taking <em>5 common</em> from 
and <em>y common</em> from 
:
Now taking 
common:
can be written as 
Now, calculating the sum:
Taking <em>LCM</em> and solving:
Hence, answer is .
Assume the secret number is x.
"Al doubled the number and added 15 to the result. He got 51."
means 2x+15=51
solving for x:
2x+15=51
2x=51-15
2x=36
x=18
"Beverly did the same operations with their number, but in the reversed order." means she first added 15 to the number, then she doubled the result,
that is she performed the operation:
First: x+15
then: 2(x+15)
since we found x=18, then we have 2(x+15)=2(18+15)=2*33=66
Answer: 66
