HELP!!WILL GIVE BRAINLIEST
vazorg [7]

Answer:

m∠A = 100

m∠C = 50

Step-by-step explanation:

let 'x' = m∠A

let 'x/2' = m∠C

x + x/2 + 30 = 180

3/2x = 150

x = 150(2) / 3

x = 300/3

x = 100

m∠A = 100°

m∠C = 100/2 or 50°

Rewrite each expression as a polynomial in standard form: x^2-5x+6 ÷ x-3 + x^3-1 ÷ x-1
iragen [17]

Answer:

So in standard form equation will be x^2+2x-1

Step-by-step explanation:

We have given expression \frac{x^2-5x+6}{x-3}+\frac{x^3-1}{x-1}

Let first we solve first part of the expression

So \frac{x^2-5x+6}{x-3}=\frac{x^2-3x-2x+6}{x-3}=\frac{(x-3)(x-2)}{x-3}=x-2

Now second part \frac{x^3-1}{x-1}

We know the algebraic identity a^3-b^3=(a-b)(a^2+ab+b^2)

So by using this identity

\frac{x^3-1}{x-1}=\frac{(x-1)(x^2+x+1)}{x-1}=x^2+x+1

Now adding first and second part

x-2+x^2+x+1=x^2+2x-1

So in standard form equation will be x^2+2x-1

Identify an expression that is equivalent to 0.3(12y)
lutik1710 [3]
3.6y is the answer. If you multiply the 0.3 times the 12 it equales 3.6 and add the y because it’s a variable.

Can you help me????????
aev [14]
Check the picture below.

now, if AC is that much, recall, BD is the midsegment, thus AB = BC, so AB is just one of the equal halves of AC, so, AB is AC/2.
