Answer:
14x-12
Step-by-step explanation:
Simplify (2x-3)(7x+4).
Expand the brackets. Remember brackets mean to multiply.
We multiply the 2x and the 7x to get 14x and we multiply the -3 by 4 to get -12 as shown below;
(2x-3)(7x+4)
14x-12
Answer: 17.832 kg
Solution: (4458 grams)*(4 books)*
= 17.832 kg
Picturing the tent helps, but we can actually solve this question using simple algebra and no knowledge of triangles.
The key is this function:
(b/h) = 2/√3
We want to get h by itself. First, multiply both sides by h:
b = h(2/√3) Now multiply both sides by the reciprical, (√3/2)
(√3/2) b = h
Therefore, the answer is C) h= b(√3/2)
Answer:
f(7) = 22 or x =2
Step-by-step explanation:
- f(x) = 3x + 1
- f(7) = 3(7) + 1
- f(7) = 21 + 1
- f(7) = 22
<u>Or if the equation meant it like this:</u>
- f(x) = 3x + 1
- 7 = 3x + 1
- 6 = 3x
- 2 = x
