Answer:

B. Lynden

Step-by-step explanation:

4(2x+2) - 2(x + 2) = 10 - 3(x +2)

To use the distributive property, you multiply the terms inside the parentheses by the number outside them.

8x + 8 - 2x - 4 = 10 - 3x - 6

A is wrong. Gregory used the addition property incorrectly. He should have gotten

4(2x + 2) + (x + 2) = 10

C is wrong. Whitney used the distributive property incorrectly. She made a mistake when distributing the -2 in -2(x + 2). She should have gotten

8x + 8 - 2x - 4 = 10 - 3x - 6

D is wrong. David combined like terms incorrectly. 10 and 3x are not like terms. He should have gotten

4(2x + 2) - 2(x + 2) = 4 - 3x

What are the partial products that resault from multiplying 15×32

Eva8 [605]

Answer:

Partial products are 300, 150, 20 and 10. The value of 15×32 is 480.

Step-by-step explanation:

We need to find the partial products of 15×32.

First write each number as the sum of their place values.

$15=10+5$

$32=30+2$

Now, write 10 and 5 in first row, and 30 and 2 in first column as shown below:

10 5

30 30×10=300 30×5=150

2 2×10=20 2×5=10

Therefore partial products are 300, 150, 20 and 10.

Add these partial product to get the value of product.

$15\times 32 = 300+150+ 20+10$

$15\times 32 = 480$

The value of 15×32 is 480.

Find all missing angles.

dimaraw [331]

Answer/Step-by-step explanation:

✅m<1 = 180 - 52° = 128° (consecutive interior angles)

✅m<2 and 52° are alternate interior angles. Alternate interior angles are congruent.

Therefore:

m<2 = 52°

✅m<3 and 47° are alternate interior angles. Alternate interior angles are congruent.

Therefore:

m<3 = 47°

✅m<4 = 180 - m<3 (linear pair)

m<4 = 180 - 47 (substitution)

m<4 = 133°

✅m<5 = 180 - (52 + 47) (angles on a straight line)

m<5 = 81°
