Answer:
Anna's number could be 5 and it could be 6.
Step-by-step explanation:
Let Anna's number be represented by x.
If Bill squared her number followed by subtracting 11 times her number, and adding 4, then he would get -26.
This implies that:
This is a quadratic equation and we can solve for x by factorization.
=> x = 5 and x = 6
Anna's number could be 5 and it could be 6.
Answer:
375
Step-by-step explanation:
<h2>HOPE THIS HELPS </h2>
The answer to the question is letter C. 4(x + 3). The expression means that the sum of x and 3 is multiplied by 4. This expression should be equal or greater than 28. All the other choices do not satisfy the inequality.
The surface area of the square bottom = L x W = 7 x 7 = 49 cm^2
The area for one of the triangles = 1/2 x base x height = 1/2 x 7 x 9 = 31.5 cm^2
There are 4 triangles, the total area for the triangles = 31.5 x 4 = 126 cm^2
Total area = base + triangles = 49 + 126 = 175 cm^2
Answer:
[(sec^2)(x)]. [e^tan(x)]
Or
[e^(tan(x))]/[(cos^2)(x)].
Step-by-step explanation:
d/dx(e^tan(x))
From the low:
[(d/du)(e^u)]=[(d/du)(u)]. [ln(e)]. [e^u]
=[(sec^2)(x)]. [e^(tan(x))]. [ln(e)]
=[(sec^2)(x)]. [e^(tan(x))]
or
[e^(tan(x))]/[(cos^2)(x)].
Because
(cos^2)(x)=1 / (sec^2)(x)
