The answer is D because once you multiply length times width your answer is 138.18
Answer:
y=5x^2+30x+58
y=−x^2+8x−26
Step-by-step explanation:
Vertex form is y = a(x – h)^2 + k, where (h, k) is the vertex.
Standard for is Ax + By = C
simply rewrite the equations using the formulas
Answer:
y = 2x -5
Step-by-step explanation:
Given points: (0,-5) (1,-3)
(x1, y1) = (0,-5)
(x2, y2) = (1,-3)
Calculate the slope:
m = (y2 - y1)/(x2 - x1)
m = [-3 - (-5)] / [1 - 0]
m = (-3 + 5) / 1
m = 2/1 = 2
Next, the y-intercept is the value of y when x = 0. One of your given points is the y-intercept, (0, -5). The y-coordinate is the value of b.
Therefore, the linear equation is: y = 2x -5

Answer:
x= -3
Step-by-step explanation:
Given: 5(x+5) = 10
Find: x
Set the equation up.
5(x+5) = 10
Simplify.
5x + 25 = 10
Subtract 25 from both sides.
5x = -15
Divide to isolate the variable.
x = -3.
(10 elements..........) 2^(10)<span>=<span>1024
</span></span><span>A discrete set with n elements has 2^n subsets. 2^n=1024 implies there are n=10 elements in this set. Any subset with 0 through n-1 elements is a proper subset of the set, as in each of those cases there exists at least one element of the set that is not in the subset, which is the requirement to be a proper subset. Therefore, we have 1023 proper subsets.</span>
