Answer:

mZB= 74

Step-by-step explanation:

ZB+ZA=180

3X-23+2X-12=180

5X-35=180

5X=180+35

5X=215 (then divide both sides by 5 to x be left alone.)

X=43....so ZB=2(43)-12

=86-12=74

A^2-12a+36 Factor. Check by expanding.

Jlenok [28]

a2 + 6a + 6a + 36

 a • (a+6)

 6 • (a+6)

 (a+6) • (a+6)

Multiply (a+6) by (a+6)

The rule says : To multiply exponential expressions which have the same base, add up their exponents.

The product is therefore, (a+6)(1+1) = (a+6)2

Final result : -1 • (a + 6)2

What is the percent of increase from 25 to 35?

katen-ka-za [31]

X - the percent increase

$25+25x=35 \ \ \ |-25 \\
25x=10 \ \ \ |\div 25 \\
x=\frac{10}{25} \\
\Downarrow \\
x=\frac{10}{25}=\frac{10 \times 4}{25 \times 4}=\frac{40}{100}=40\%$

The answer is C. 40% increase.
