Area = length * width
(10x + 6)(9x + 8)
Multiple (I used rainbow method)
10x * 9x = 90x^2
10x * 8 = 80x
6 * 9x = 54x
6 * 8 = 48
90x^2 + 80x + 54x + 48
90x^2+ 134x + 48
The area is 90x^2 + 134x + 48

Which is a reasonable first step that can be used to solve the equation 2(x + 6) = 3(x - 4) + 5?
olasank [31]

Answer:

Distribute 2 to (x + 6) and 3 to (x - 4)

Step-by-step explanation:

2(x + 6) = 3(x - 4) + 5

The first step is to distribute on both sides

2x+12 = 3x-4 +5

We have to distribute to all terms inside the parentheses

Write 25/60x15/50 in lowest terms
Serggg [28]
25/60 x 15/50
(25x15) (60x50) = 375/3000 = 1/8
Because 3000 divided by 375 is 8 so it would be 1/8

Is DEF a right triangle? True or false
umka2103 [35]
Short answer = false
Remark

If it is a right triangle, it will obey the Pythagorean Equation. a^2 + b^2 = c^2. Let's see if it does.

Equation
a^2 + b^2= c^2
c must be the longest line. (Hypotenuse)

Givens
a = 24
b = 17
c = 40

Sub and Solve
a^2 + b^2 = c^2
17^2 + 24^2 = c^2 [We'll see if this comes out to 40]

289 + 576 = c^2
865 = c^2 which is no where near what 40^2 equals. 40^2 = 1600

Short answer False

Square root of 865 = (865)^1/2 = 29.4

Solve the equation 5x=3x^2+1
Arte-miy333 [17]

Answer:

-1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5x=6x+1

Step 2: Subtract 6x from both sides.

5x−6x=6x+1−6x

−x=1

Step 3: Divide both sides by -1.

−x

/-1=1/-1

x=-1
