Which equation correctly applies the distributive property?

lesantik [10]

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Distributive law is defined as

$a\times (b+c+d)=a\times b+a\times c+a\times d$

According to option'A', we get that

a =- 3

b = 6

c = 0.4

d = 0.08

So, it becomes,

$-3\times (6.48)=-3\times 6+(-3)\times 0.4+(-3)\times 0.08$

Hence, option 'A' is correct.

Can y’all please help if you know this I’m kinda lost !

Zepler [3.9K]

Answer:

Part A) x = 5

Part B) B = 113 degrees, C = 95 degrees. E = 95 degrees

Step-by-step explanation:

Part A:

We know that the sum of all angles in a pentagon are 540 degrees.

We already have two angles: 113 and 124 which add up to 237.

Make an equation out of all the information.

237 + 98 + 3x + 19x - x = 540

3x + 19x - x = 105

21x = 105

x = 5

Part B:

Substitute 5 for each x

measure B: 98 + 3x = 98 + 3*5 = 98 + 15 = 113

measure C: 100 - x = 100 - 5 = 95

measure E: 19x = 19* 5 = 95
