For this, I will be factoring by grouping to solve for y.
Firstly, factor y^3 + 5y^2 and -9y - 45 separately, Make sure that they have the same quantity on the inside:
Now you can rewrite it as . However we are not finished factoring.
Now with y^2 - 9, we will apply the difference of squares rule, which is . Apply it as such:
Now that it is completely factored, we can apply the Zero Product Property and solve for y:
<u>In short, y = -5, -3, and 3.</u>
Answer:
20
Step-by-step explanation:
She only has 20 bags of flower petals, so she cannot create more than that. Because 40 is divisible by 20, she can make 20 bowls.
Answer:
8
Step-by-step explanation:
since this is a right triangle, we can use trig formulas
cos theta = adj / hyp
cos 37 = x /10
10 cos 37 =x
7.9863551=x
To the nearest integer
8=x

Answer:
A = 20 cm^2
Step-by-step explanation:
We can find the area of a triangle from
A = 1/2 bh
A = 1/2 8*5
A = 20 cm^2
