O B. (x - 4)(x - 16)
O C. (x-8)(x-8)
O D. (x + 4)(x + 16)

Answers

x^2 + 16x + 64
x + x = 16
x^2 = 64
Therefore x = 8
(X + 8)(x + 8)

Solution: A

Answer:

A. (x+8)(x+8)

Step-by-step explanation:

F: x*x=x^2

O: x*8=8x

I: 8*x=8x

L: 8*8=64

x^2+8x+8x+64 = x^2+16x+64

Construct a street that has an x-intercept of 6 and a slope of 4. what is the y-intercept?

Answers

Answer: CAN U MARK BRAINLIST!!!!! You've probably already seen the basic method for graphing straight lines; namely, make a T-chart, plot some points, put your ruler against them, and draw the line. But the "nice" form of a straight line's equation (being the slope-intercept form, y = mx + b) can make graphing even simpler and faster.

Given two points (x1, y1) and (x2, y2), the formula for the slope of the straight line going through these two points is:

\small{ m = \dfrac{y_1 - y_2}{x_1 - x_2} }m=

...where the subscripts merely indicate that we have a "first" point (whose coordinates are subscripted with a "1") and a "second" point (whose coordinates are subscripted with a "2"); that is, the subscripts indicate nothing more than the fact that we have two points that we're working with. Note that which point we pick as the "first" point is irrelevant; if we pick the other point to be "first", the subtractions will be reversed, but we'll still get the exact same value for the slope:

is y less than or equal to 1

Answers

Answer: Y is equal to 1

Step-by-step explanation:

If any variable is by itself like for example 1 + y, that variable would equal one because it's all by itself so it attomatically equals 1. But if the variable was with another number like 1y, then it would mean you have to multiply it by whatever why would equal.

The equation SA = 6s2 can be used to calculate the surface area, SA, of a cube with side length s. What is the surface area, in square meters, of a cube with a side length of 0.5 meter?

Answers

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

1.5 square meters

»»————- ★ ————-««  

Here’s why:  

As given in the question you have asked, the surface area of a cube can be found with:

[tex]SA=6s^2\\\\SA - \text{Surface Area}\\\\S- \text{A given side length.}[/tex]

⸻⸻⸻⸻⸻

We are given the side length of 0.5 meters. This means that we have to substitute the variable 's' for '0.5' to find the surface area.

⸻⸻⸻⸻⸻

[tex]\boxed{\text{Surface Area of a cube with a side length of 0.5 meters:}}\\\\------\\\\SA= 6(0.5)^2\\\\\rightarrow SA=6(0.25)\\\\\rightarrow \boxed{SA=1.5}\\\\------[/tex]

⸻⸻⸻⸻⸻

[tex]\text{The surface area of the cube should be }\boxed{\text{1.5m}^2\text{.}}[/tex]
