Answer:
3x² - 6
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x), thus
f(x) + g(x)
= 2x² + 1 + x² - 7 ← collect like terms
= 3x² - 6
The side labeled "a" is made the longer side. These are the two congruent sides. So a > b.
We are told that the longer side is 6.3, so a = 6.3, meaning that
2a+b = 15.7
2(6.3)+b = 15.7
12.6+b = 15.7
b = 15.7-12.6
b = 3.1
The triangle has sides of: 6.3, 6.3, 3.1
The perimeter is 6.3+6.3+3.1 = 15.7
Going back to the question "which equation can be used to find the length of the base?", it sounds like either you were given a list of multiple choice answers, or you just fill in the blank. If multiple choice, then try to see which answer matches with what I wrote above. If fill in the blank, then I would just enter either 2(6.3)+b = 15.7 or 12.6+b = 15.7
10 + -70
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
We are starting with 51
50x10=50
1x1=1
since there were 0.21 seconds, we first have to find the tenths place.
0.1x2=0.2
now that we found the tenths place, we need to find the hundredths place
0.01x1=1
FINAL ANSWER
(5 x 10) + (1 x 1) + (2 x 0.1) + (1 x 0.01)
Answer:
y = 2/5x - 2
Step-by-step explanation:
Subtract x to the other side to get -5y = -2x + 10. Divide -2x + 10 by -5 to get the answer.
