Answer: at end of explanation
Step-by-step explanation:
First simply operate the e's, so get common factor and (- 56 - 23)e = -24. This leaves you with -79e = -24. Then move the number multiplying e to dividing the other side, so e = -24 / -79, wich results in 0.8 period. So your result rounded to 2 decimal places is 0.89.
1.) Convert the measurements of Naomi's pets so that the two has the same unit of measurements. I will use cm.
1 mm = .01 cm;
Therefore: 40 mm = 4 cm is the length of the fish
2.) Subtract the pets' measurements:
25 cm - 4 cm = 21 cm
3.) Therefore, Naomi's guinea pig is 21 cm longer than her fish.
Answer:
x = 2 and y = 1
Step-by-step explanation:
A) 5x+y=11
B) x - y = 1.
(Solving by substitution)
B) x - 1 = y
A) 5x + (x -1) = 11. 6x-1=11. 6x = 11+1
6x = 12
x = 12/2. x = 2
B. 2 - 1 = y. y = 1
Answer:
Yes!
Step-by-step explanation:
In Pythagorean Triples, the two legs always have to add up to be a greater number than the hypotenuse. In this case, 12 and 16 are the legs and 20 is the hypotenuse. The sum of 12 and 16 is 28. That is more than 20, so 12, 16 and 20 make a right triangle. I hope this helps you!
Answer:
(a - 3) • (a - 4)
Step-by-step explanation:
The first term is, a2 its coefficient is 1 .
The middle term is, -7a its coefficient is -7 .
The last term, "the constant", is +12
Multiply the coefficient of the first term by the constant 1 • 12 = 12
Find two factors of 12 whose sum equals the coefficient of the middle term, which is -7 .
-12 + -1 = -13
-6 + -2 = -8
-4 + -3 = -7 That's it
Rewrite the polynomial splitting the middle term using the two factors, -4 and -3
a2 - 4a - 3a - 12
Add up the first 2 terms, pulling out like factors :
a • (a-4)
Add up the last 2 terms, pulling out common factors :
3 • (a-4)
Add up the four terms
(a-3) • (a-4)
Really hope this helps :)
