Answer:
<u>Clare will need 8 little cubes of 1/2 edge length to build a larger cube that has 4 inches of edge length.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Little wooden cubes edge length = 1/2 inch
Larger cube edge length = 4 inches.
2. How many little cubes does Clare need to build the larger cube?
We can calculate the number this way:
Number of little cubes for building a larger cube = 4/0.5 (1/2 = 0.5)
Number of little cubes for building a larger cube = 8
<u>Clare will need 8 little cubes of 1/2 edge length to build a larger cube that has 4 inches of edge length.</u>

<h2>MISSING NUMBER</h2>
Given:
Choices:
- a. percent
- b. rate
- c. base
- d. percentage
Answer:
- The <u>rate</u> is the missing term. Thus, option <u>b. rate</u> is the best answer.
Solving:
Rate =
Base = 50
Percentage = 25
Just convert the number into a percent since rate is the missing term. Always remember that rate have a percent sign (%).
Answer:
x = -2 or x=-5
Step-by-step explanation:
sqrt(x+6)-4 = x
sqrt(x+6) = x+4
square both sides
x+6 = x²+8x+16
x²+7x+10 = 0
(x+2)(x+5) = 0
x = -2 or x=-5
Substitute in original equation
x=-2 +/- sqrt(-2+6)-4 = 2-4 = -2 checks
x=-5 +/- sqrt(-5+6)-4 = -1-4 = -5 checks
