Answer:
d
Step-by-step explanation:
(5x + 3 ) - (x + 2 )
distribute (5x + 3) by 1 and (x - 2) by - 1
= 5x + 3 - x - 2 ← collect like terms
= 4x +1 → d

Answer:
- 113.0 cm²
- 2464.0 in²
- 95.0 ft²
Step-by-step explanation:
1. The area of a circle is given by the formula ...
A = πr² . . . . . where r is the radius
The radius is shown as 6 cm, so the area is ...
A = (3.14)(6 cm)² = 113.0 cm²
__
2. The radius is shown as 28 in. We note that this is a number divisible by 7, so we choose 22/7 for π.
A = (22/7)(28 in)² = 2464 in² . . . . see comment
__
3. The radius is half the diameter, so is 11/2 = 5.5 ft. Then the area is ...
A = (3.14)(5.5 ft)² = 95.0 ft²
_____
<em>Additional comment</em>
If you use a more exact value of π for problem 2, the area is 2463.0 in². If you use 3.14 as the value of π, the area rounds to 2461.8 in². For these values of pi (3.14 or 22/7), the answer is only good to about 3 significant digits. 2464 has more significant digits, so digits beyond the first 3 may be in error.

Answer:
Step-by-step explanation:
18.4 + 8w = 6(-4.6 + 9w)
18.4 + 8w = (-4.6 * 6 + 9w * 6)
18.4 + 8w = (-27.6 + 54w)
18.4 + 8w + -54w = -27.6 + 54w + -54w
18.4 + -46w = -27.6 + 54w + -54w
18.4 + -18.4 + -46w = -27.6 + -18.4
Combine like terms: 18.4 + -18.4 = 0.0
0.0 + -46w = -27.6 + -18.4
-46w = -27.6 + -18.4
-27.6 + -18.4 = -46
-46w = -46
w = 1
Simplifying
w = 1
sum of the four consecutive integers is 238; The next step is to represent the four consecutive integers using the variable “ n “. Let n be the first integer. Since the four integers are consecutive, this means that the second integer is the first integer increased by 1 or {n + 1}.
