Answer:
5
Step-by-step explanation:
A1 = (h*b)/2
= ( (8-1)*(3-1) ) /2
= 7
A2 = (h*b)/2
= (2*2) /2
= 2
Ablue = A1 - A2
= 7 - 2
= 5

Answer:
Kamille paid $34.88 for her outfit after tax.
Ms. Roth will pay $59.16 in total.
Step-by-step explanation:
Kamille brought a new outfit that cost $32.00. The tax rate is 9%. How much did she pay for the outfit after tax?
32.00 x 0.09 = 2.88
32 + 2.88 = 34.88
Ms. Roth went to I-Hop for breakfast. She ordered pancakes for $5.00, eggs for $3.50, and orange juice for 42.50. if she tips the waiter 16%, how much will she pay in total?
5 + 3.5 + 42.50 = 51
51 x 0.16 = 8.16
51 + 8.16 = 59.16
Answer:
OR ![x =\frac{17}{18} +\frac{-1}{18} \sqrt{3349}](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B17%7D%7B18%7D%20%2B%5Cfrac%7B-1%7D%7B18%7D%20%5Csqrt%7B3349%7D)
Step-by-step explanation:
9x2−17x−85=0
For this equation: a=9, b=-17, c=-85
9x2+−17x+−85=0
Step 1: Use quadratic formula with a=9, b=-17, c=-85.
![x =\frac{-b + \sqrt{b^{2}-4ac } }{2a}](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B-b%20%2B%20%5Csqrt%7Bb%5E%7B2%7D-4ac%20%7D%20%7D%7B2a%7D)
![x =\frac{-(-17)+\sqrt{(-17)^{2} -4(9)(-85)} }{2(9)}](https://tex.z-dn.net/?f=x%20%20%3D%5Cfrac%7B-%28-17%29%2B%5Csqrt%7B%28-17%29%5E%7B2%7D%20-4%289%29%28-85%29%7D%20%7D%7B2%289%29%7D)
