Answer:
11.74b + 72.16
Step-by-step explanation:
In this question, we're going to simplify the expression.
Solve:
1.9b + 8.2(8.8 + 1.2b)
Use the distributive property.
1.9b + 72.16 + 9.84b
Combine like terms.
11.74b + 72.16
Since we can't simplify any further, 11.74b + 72.16 would be your answer.
Answer:
The answer for this question is 12yd
The quadratic term is 2x^2.
Answer:
I think your answer would be 12x - 2
If this is wrong then im sorry
Answer:
8.7 cm
Step-by-step explanation:
The question is a 2-two-step Pythagoras theorem. (c^2 = a^2 + b^2)
Consider as such, If I were to draw a diagonal line along the base of the cube what is the length of the diagonal line. To find out that we use the theorem. We can substitute a for 5 and b for 5 as well. So
a^2 +b^2 = c^2
5^2 + 5^2 = c^2
25 + 25 = c^2
√50 = c
Then since the line side of the cube is on a 3d angle we need to do the same process again but now using the imaginary diagonal line that we just calculated and the height (5).
a^2 +b^2 = c^2
√50^2 + 5^2 = c^2
50 + 25 = c^2
√75 = c
c = 8.6602...
<em>when rounded to 1 d.p.</em>
c = 8.7
Line AB is 8.7 cm long.
