geniusboy [140]3 years ago
4 0

Answer:

- 4x² - 8x - 3

Step-by-step explanation:

We want to calculate

1 - (2x + 2)² ← expand using FOIL

= 1 - (4x² + 8x + 4) ← distribute parenthesis by - 1

= 1 - 4x² - 8x - 4 ← collect like terms

= - 4x² - 8x - 3

Solve for 52=4(8m-5)-8(m-6)
ira [324]

Answer:

  • <u>m = 1</u>

Explanation:

1. <u>Given</u>: 52 = 4(8m - 5) - 8(m - 6)

2. <u>Distributive property</u> on the two binomials: multiply 4 times each term inside the first binomial and multiply - 8 times each term inside the second binomial:

  •    52 = 32m - 20 - 8m + 48

3. <u>Combine like terms</u>: 32m and -8m are a pair of like terms; - 20 and + 48 are other pair of like terms:

  • 52 = 24m + 28

4. <u>Subtraction property of equality</u>: subtract 28 from both sides:

  • 52 - 28 = 24m

5. <u>Simplify</u>:

  • 24 = 24m

6. <u>Division property of equality</u>: divide each side by 24

  • 24/24 = m

7. <u>Simplify</u>:

  • 1 = m

8. <u>Symmetric property</u>:

  • m = 1

I've attached the question in the picture below.
ololo11 [35]

at a map scale of 1:1500, 12 centimeters on the map is equivalent to 1.8 kilometers on the ground.

step-by-step

since the scale is 1 to 15,000 you simply multiply it by the 12 cm

12cm × 15,000 = 180,000

but you still have to convert it to kilometers (the measurement on the ground).

to go from centimeters to kilometers move the decimal 5 place values to the left.

<u>final</u><u> </u><u>answer</u>

1.8 kilometers
