Answer:
x = 4
Step-by-step explanation:
Solution:
-3(4x + 3) + 4(6x + 1) = 43
-12x - 9 + 24x + 4 = 43
12x - 5 = 43
12x = 43 + 5
12x = 48
x = 48 / 12
Therefore, x = 4

Answer:
8(3j -2)
4(6j -4)
Step-by-step explanation:
24j - 16
Rewriting
8*3*j - 8*2
Factor out the greatest common factor
8(3j -2)
We can also factor out 4
4*6j - 4*4
4(6j -4)
Step-by-step explanation:
step 1: given= 6*0=0
step 2: Use the distributive property
step 3: Substitute
step 4: -
step 5: Subtract 60 from both sides
step 5: simplify
The difference in area between the top surfaces of the two cakes is 28.26 inches²
<h3>Area of a circle</h3>
where
r = radius
Therefore,
area of top layer = πr²
d = 2r
r = d / 2
r = 8 / 2
r = 4 inches
area of top layer = 3.14 × 4²
area of top layer = 3.14 × 16
area of top layer = 50.24 inches²
area of the bottom layer = πr²
r = 10 / 2 = 5 inches
area of the bottom layer = 3.14 × 5²
area of the bottom layer = 3.14 ×25
area of the bottom layer = 78.5 inches²
Difference in area between the top surfaces of the two cakes can be found as follows:
- 78.5 - 50.24 = 28.26 inches²
