Answer
7. 30
8. 54
Step-by-step explanation:
For 7 do 2x+3x=90 because it is a right angle
then solve for x and get 15
to get the angle you are looking for multiply 2 by 15
and get the answer 30
For 8 to find the value of x you would need to...
add (4x+6) + (11x-6)= 180 because 180 is a straight angle.
Then simply solve for x and get 15x=180 which equals 12
The to get the angle you plug it in to (4x+6) and get the answer 54
The dekameter (or decameter) first needs to be a translated into how many
the meters. deka means 10, so a dekameter it must be 10 meters. So we have to
divide 250 by 10, and then we will come up with 25 dekameters.
hope that helps!!
Answer: 0.8 in^2 (as in inches squared)
Step-by-step explanation:
1. DO NOT FOCUS ON THE 1 ON THE LEFT! JUST FOCUS ON THE BASE AND HEIGHT!
2. Area= b*h
3. Plus in your numbers. Area=1*0.8.
4. Multiply. Area=0.8in^2.
Upon slight rearrangement...
54xy+18y+45x+15 now factor 1st and 2nd pair of terms
18y(3x+1)+15(3x+1) which is equal to
(18y+15)(3x+1) and you can further factor the first binomial factor
3(6y+5)(3x+1)
