Answer: 12:14
Step-by-step explanation:
Multiply both sides by 2
Answer:
price of oranges is 6.63
Step-by-step explanation:
1)59.53-6.49=53.04
2) 53.04/8=6.63
Seeing that both triangles are side by side and share a side, we know that that side of both triangles is congruent.
Then when you look at the angles, you will see that one on each triangle has one curved line. This one curved line shows that these angles are congruent.
There is then the two curved lines you can find on both triangles as well. This shows that both those angles are congruent.
With this information, you should be able to tell that two angles of the triangles are congruent, and one side of both triangles are congruent, with the order that these are shown on the triangles being an angle, then a side, then another angle, the answer would be ASA, or angle, side angle.
8y^2 + 6y + 1
List the factors of a and c.
a: 1 x 8, 2 x 4
c: 1 x 1
Since c is positive find factors from the list that will add up to the absolute value of b.
1, 1, 2, and 4 -----> (1 x 2) + (1 x 4) = 6
Arrange these four factors accordingly. Because both b and c are positive, both parentheses will have a plus sign.
( + )( + )
Ask yourself, "Which two factors with y as a variable will multiply to give me 8y^2?" Fill in the parentheses.
(4y + )(2y + )
Use trial and error(by FOILing).
(4y + 1)(2y + 1)
Check answer.
(4y)(2y) = 8y^2
(4y)(1) = 4y
(2y)(1) = 2y
(1)(1) = 1
Set up as a polynomial.
8y^2 + 4y + 2y + 1
Combine like-terms.
8y^2 + 6y + 1
So 8y^2 + 6y + 1 is equal to (4y + 1)(2y + 1).
Answer:
82.8 m^2
Step-by-step explanation:
Find area of front-facing triangle: 1/2(6)(8.8)=26.4
26.4*2=52.8
Find area of side-facing triangle: 1/2(2)(9)=9
9*2=18
Find area of rectangular base: 6(2)=12
Add it all up: 52.8+18+12=82.8
Therefore, 82.8 m^2
