7 - 9 + (9 - 5)^2-4x 6/-6+8-3x10? Can y'all help me? I know I just asked but I'm really bad at math!!!!

What is the surface area of the cube with the given edge length, s?

iren [92.7K]

A cube has 6 sides.
first calculate the area of 1 side and then multiply it by 6

the area for one side = S^2 ( or SxS)

15^2 = 15 x 15 = 225 square inches

now multiply that by 6:
225 x 6 = 1350 square inches total

the answer is B.

A frog made three jumps .The first was 12 5/6 inches.The second one was 8. 3/6 inches.The third jump was 15 1/6 inches.What was

lutik1710 [3]

Answer:

36 1/2 Inches

Step-by-step explanation:

I found this by first adding the fractions up, which gets us 9/6 or 1 and 3/6 or 1/2

12+8+15+1 1/2

12+8=20

20+15=35

35+1 1/2= 36 and 1/2 Inches

Hope this helped

Answer:

69

Step-by-step explanation:

A hexagon has 720 degrees in total. You add allthe numbers which is 513 degrees. Then you subtract them which is 207 degrees. Finally you divide 207 by 3 which is 69 :)

If f(x) is a third degree polynomial function and g(x) = f(–2x), which of the following is NOT true?

valina [46]

Answer:

f(x) and g(x) have the same x-intercepts (is <em>not true</em>)

Step-by-step explanation:

g(x) is a reflection across the y-axis and a horizontal compression of f(x). In general those transformations will move the x-intercepts. (The y-intercept and the number of x-intercepts will remain unchanged.)

_____

<em>Comment on the question/answer</em>

f(x) = x^3 is a 3rd degree polynomial. When transformed to g(x) = -8x^2, its only x-intercept (x=0) remains the same. The answer above will not apply in any instance where the only x-intercept is on the line of reflection. (The question is flawed in that it does not make any exception for such functions.)

Rewrite the expression $6j^2 - 4j 12$ in the form $c(j p)^2 q$, where $c$, $p$, and $q$ are constants. What is $\frac{q}{p}$

solniwko [45]

$Rewrite the expression 6j^2 - 4j + 12$ in the form $c(j + p)^2 + q$, where $c$, $p$, and $q$ are constants. What is $\frac{q}{p}$$

The ratio of $\frac{q}{p}$ = - 34

How to solve such questions?

Such Questions can be easily solved just by some Algebraic manipulations and simplifications. We just try to make our expression in the form which question asks us. This is the best method to solve such questions as it will definitely lead us to correct answers. One such method is completing the square method.

Completing the square is a method that is used for converting a quadratic expression of the form $ax^{2} + bx + c$ to the vertex form

$a(x - h)^{2} + k$ . The most common application of completing the square is in solving a quadratic equation. This can be done by rearranging the expression obtained after completing the square: $a(x + m)^{2} + n$ , such that the left side is a perfect square trinomial
