Answer:

15w - 10x + 30.

Step-by-step explanation:

-5(2x - 3w - 6)

= (-5 * 2x) + (-5 * -3w) + (-5 * -6)

= -10x + 15w + 30

= 15w - 10x + 30.

Hope this helps!

Answer:

<h2>- 10x + 15w + 30</h2>

Step-by-step explanation:

- 5(2x - 3w - 6)

Multiply each term in the parentheses by -5

- 5 \times 2x - 5 \times ( - 3w) - 5 \times ( - 6)

Calculate the product

- 10x - 5 \times ( - 3x) - 5 \times ( - 6)

Multiplying two negatives equals a positive ( - ) \times ( - ) = ( + )

- 10x + 5 \times 3w - 5 \times ( - 6)

Calculate the product

- 10x + 15w - 5 \times ( - 6)

Multiply the numbers

- 10x + 15w + 30

Hope this helps..

Best regards!!

3x2 + 2(x2 – 20) = 16 - 2x2
lana66690 [7]

3x(2) + 2(2x - 20) = 16 - 2x(2)

6x + 4x - 40 = 16 - 4x

10x - 40 = 16 - 4x

14x - 40 = 16

14x = 56

x = 4

Hope this helps! ;)

Which sequence represents an arithmetic sequence?
Sergio039 [100]

we know that

arithematic sequence will always have common difference

(a)

−5, −7, −10, −14, −19, …

we can see that

d_1=-7+5=-2

d_2=-10+7=-3

they are not equal

so, this is not arithematic sequence

(2)

1.5, −1.5, 1.5, −1.5, …

we can see that

d_1=-1.5-1.5=-3

d_2=1.5+1.5=3

they are not equal

so, this is not arithematic sequence

(3)

4.1, 5.1, 6.2, 7.2, …

we can see that

d_1=5.1-4.1=1

d_2=6.2+5.1=1.1

they are not equal

so, this is not arithematic sequence

(4)

−1.5, −1, −0.5, 0, …

we can see that

d_1=-1+1.5=0.5

d_2=-0.5+1=0.5

they are equal

so, this is arithematic sequence

An angle measured 10 degrees less than the measure of its complementary angle. Find the measure of both angles
Mazyrski [523]

Answer:

The measure of the angles are 40 degrees and 50 degrees

Step-by-step explanation:

Let

x ----> the measure of one angle in degrees

y ----> the measure of the complementary angle in degrees

we know that

If two angles are complementary, then their sum is equal to 90 degrees

so

x+y=90 ----> equation A

we have that

x=y-10 ----> equation B

Substitute equation B in equation A and solve for y

(y-10)+y=90\\2y-10=90\\2y=100\\y=50

Find the value of x

x=50-10=40

therefore

The measure of the angles are 40 degrees and 50 degrees
