Answer:
h = (2 A)/(b_1 + b_2)
Step-by-step explanation:
Solve for h:
A = 1/2 h (b_1 + b_2)
A = 1/2 h (b_1 + b_2) is equivalent to 1/2 h (b_1 + b_2) = A:
1/2 h (b_1 + b_2) = A
Divide both sides by 1/2 (b_1 + b_2):
Answer: h = (2 A)/(b_1 + b_2)
Answer:
The simplified form of the expression is 
.
Step-by-step explanation:
The expression is:
The division rule of exponents is:
The negative exponent rule is:
Simplify the expression as follows:
![\frac{x^{-3}\cdot y^{2}}{x^{4}\cdot y^{6}}=[x^{-3-4}]\times [y^{2-6}]](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B-3%7D%5Ccdot%20y%5E%7B2%7D%7D%7Bx%5E%7B4%7D%5Ccdot%20y%5E%7B6%7D%7D%3D%5Bx%5E%7B-3-4%7D%5D%5Ctimes%20%5By%5E%7B2-6%7D%5D)
Thus, the simplified form of the expression is .
Answer:
4. 16.5 minutes 2508 words - Robert
5. 60 words (c)
6.I don't really know sorry :)
Step-by-step explanation:
4. 304 ÷ 2 = 1 minute 152 words - Robert
2508 ÷ 152 = 16.5 minutes 2508 words - Robert
5. 152 × 20 = 3040 words - Robert
483 ÷ 3 = 1 minute 161 words - Michaela
161 × 20 = 3220 words - Michaela
316 ÷ 2 = 1 minute 158 words - Laura
158 × 20 = 3160 words - Laura
= 3220 - 3160
= 60 words (c)
Please give me brainliest ;)
