Answer:
hmm i am not sure sorry XD
Step-by-step explanation:
The square of a binomial is a pattern you would do well to remember.
.. (x +y)^2 = x^2 +2xy +y^2
Your expression has x^2 = 25a^2, so x = 5a. It also has y^2 = (b^2)/4, so y = b/2.
then the middle term is
.. 2xy = 2(5a)(b/2) = 5ab
The trinomial is
.. 25a^2 +5ab +(1/4)b^2 = (5a +b/2)^2
Answer:
y = -2
Step-by-step explanation:
Step 1: Define
-3x - y = 56
x = -18
Step 2: Substitute and solve for <em>y</em>
-3(-18) - y = 56
54 - y = 56
-y = 2
y = -2
Answer:
64 inch³
Step-by-step explanation:
3 / 2 = 1.5 radius
1.5²x π x 10 = 22.5 π = volume
22.5 π x 9/10 = 20.25π of water
= 63.6172512352
Answer:
(a)
Step-by-step explanation:
To determine if the points are a solution to the equation.
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then they are a solution.
(2, 5)
- 3(2) + 4(5) = - 6 + 20 = 14 ← True
(4, 6)
- 3(4) + 4(6) = - 12 + 24 = 12 ← False
Thus (2, 5) is the only solution to the equation → (a)
