Answer:

20x + 18

Step-by-step explanation:

We need to use the distributive property, where we essentially take the sum of the product of the outside number with each of the inside terms.

In 7(4x - 2), 7 is the outside number and 4x and -2 are the inside numbers, so:

7(4x - 2) = 7 * 4x + 7 * (-2) = 28x - 14

In 4(2x - 8), 4 is the outside number and 2x and -8 are the inside numbers, so:

4(2x - 8) = 4 * 2x + 4 * (-8) = 8x - 32

Now, we have:

28x - 14 - (8x - 32) = 28x - 14 - 8x + 32 = 20x + 18

The answer is 20x + 18.

Step-by-step explanation:

<u>Step 1: Distribute</u>

<u /> $7(4x - 2) - 4(2x - 8)$

$(7 * 4x) + (7 * -2) + (-4 * 2x) + (-4 * -8)$

$(28x) + (-14) + (-8x) + (32)$

$28x - 14 - 8x + 32$

<u>Step 2: Combine like terms</u>

$28x - 14 - 8x + 32$

$20x + 18$

Answer: $20x + 18$

Maths question on algebraic equations = due in 10 minutes

erma4kov [3.2K]

Answer:

108 degrees.

Step-by-step explanation:

2x + 16 = 3x - 12 (corresponding angles; AB parallel to CD).

16 + 12 = 3x - 2x

x = 28.

So the angle marked 3x - 12 = 3(28) - 12

= 72 degrees.

Angle y is adjacent to the angle so

y = 180 - 72

= 108 degrees.

The value of y varies directly with x. If x =3, then y=21. What is the value of x when y=105?

Goshia [24]

Answer:

x = 15

Step-by-step explanation:

given that y varies directly with x

mathematically we can express this as

y = k x , where k is a constant

step 1: find k

given x = 3 and y = 21

y = k x

21 = k (3)

k = 7

hence the equation becomes

y = 7 x

when y = 105,

105 = 7x

x = 105 / 7 = 15

How do you answer this?

gulaghasi [49]

Answer:

75.7°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relations between trig functions and sides of a right triangle. You are given all three sides of the triangle, so you can make use of at least two different trig functions to find the missing angle.

Cos = Adjacent/Hypotenuse

Tan = Opposite/Adjacent

<h3>cosine</h3>

The hypotenuse is 65, and the side adjacent to the unknown angle is 16. That tells you ...

cos(?) = 16/65

The inverse function is used to find the angle value:

? = arccos(16/65) ≈ 75.7°

<h3>tangent</h3>

The side opposite the angle of interest is 63. Then you have ...

tan(?) = 63/16

The inverse function is used to find the angle value:

? = arctan(63/16) ≈ 75.7°

_____

<em>Additional comments</em>

When using trig functions on a calculator, you need to make sure the angle mode is set to what you want. Here, we want angles in degrees, so we have set that as the angle mode. The [DEG] icon in the lower left corner of the display confirms this.

We can't tell what you're supposed to round the value to. The attachment gives enough digits for you to be able to round to whatever precision you need.
