Since a square has a complementary angle, it’s four angle in total is 360 degrees. But the angle b is given in the question and says what angle it was. So, angle b is 4x+10. What do we do about these numbers? We just created them into an equation and solve them algebraically. The way to solve it is this way:
4(4x+10) = 360
16x +40 = 360
16x= 320
X= 20

The answer is x= 20

ruslelena [56]
Hello!

Divide the amount of chairs (30) that 12 people can build by the number of hours (8) it takes to build them, to find out how many chairs they make per hour.

30 ÷ 8 = 3.75

This means that they make they make 3.75 chairs per hour. Multiply this by 100 hours.

3.75 × 100 = 375

ANSWER:

The people can build D. 375 chairs in 100 hours.

Factor the expression completely.
evablogger [386]

Answer:

Factoring the expression xy^4+x^4y^4 completely we get \mathbf{xy^4(x+1)(x^2-x+1)}

Step-by-step explanation:

We need to factor the expression xy^4+x^4y^4 completely

We need to find common terms in the expression.

Looking at the expression, we get xy^4 is common in both terms, so we can write:

xy^4+x^4y^4\\=xy^4(1+x^3)

So, taking out the common expression we get: xy^4(1+x^3)

Now, we can factor the term (1+x^3) or we can write (x^3+1) by using formula:

a^3+b^3=(a+b)(a^2-ab+b^2)

So, we get:

xy^4(1+x^3)\\=xy^4(x^3+1)\\Applying\:the\:formula\;of\:a^3+b^3\\=xy^4(x+1)(x^2-x+1)

Therefor factoring the expression xy^4+x^4y^4 completely we get \mathbf{xy^4(x+1)(x^2-x+1)}

25% of €40:00 = €<br> And explain it
Wewaii [24]

Answer:

The correct answer is €10.00

Step-by-step explanation:

50% of 40 is 20. 50% of 50 is 25, so what you do is just take 20 and multiply that by 0.5 or you can just take 40 and multiply that by 0.25.

I really hope this helps you out!
