Answer:
c
Step-by-step explanation:
the like terms are 5x and 2x
Answer:
<u>The correct answer is A. Add 4 to both sides, and then divide by 2. The solution is x = 12.</u>
Step-by-step explanation:
1. For solving the question and understand which of the statements matches with the solution, let's proceed with the equation:
2x − 4 = 20
2x - 4 + 4 = 20 + 4 (Adding 4 at both sides)
2x = 24
2x/2 = 24/2 (Dividing by 2 at both sides)
x = 12
<u>The correct answer is A. Add 4 to both sides, and then divide by 2. The solution is x = 12.</u>
Answer:
9.57 yd squared
Step-by-step explanation:
we can divide this figure into two shapes: a rectangle and a semi-circle
since we know the length and width of the rectangle, all we ahve to do is multiply them together to find the area: <u>8 yd squared</u>
for the semi-circle, we know the area is 
raduis is half the diameter so 1 yd
<u />
<u>1.57 yd squared</u>
lastly, add the area of the two figures together 8+1.57
Sqrt 5 because it’s an imperfect square. Fractions with integers are always rational and sqrt 9 is perfect so it is also an integer.
Answer:
x =52
Step-by-step explanation:
