Answer:
M<1 = 106
M<2 = 74
M<3 = 106
M<4 = 74
M<5 = 106
M<6 = 74
M<7 = 106
M<8 = 74
Step-by-step explanation:
The both equations should equal 180° when combined. So when you add like-terms you get 8x+20=180. X=20°
Answer:
P=16+2x
Step-by-step explanation:
The formula for finding the perimeter of a rectangle is P=2l+2w.
Plug the length of 8 and the width of x into the formula.
You'll get P=2(8)+2(x).
Multiply. 2•8=16 and 2•x=2x.
Your expression is P=16+2x.
I hope this helps.
Answer:
9409
Step-by-step explanation:
Let's rewrite 97 as 100 - 3.
Identity used :
<u><em>(a - b)² = a² - 2ab + b²</em></u>
Now, evaluating the expression :
⇒ (100 - 3)²
⇒ (100)² - 2(100)(3) + (3)²
⇒ 10000 - 600 + 9
⇒ 9400 + 9
⇒ 9409
