Answer:

The length of the shorter piece is $5\textrm{ ft}$ .

The length of the longer piece is $11\textrm{ ft}$ .

Step-by-step explanation:

The five-step method is GUESS method.

Given:

Length of steel beam, $L=16\textrm{ ft}$

Length of longer piece is 1 foot longer than twice the shorter one.

Unknown:

Length of longer and shorter pieces of beam.

Let the length of shorter piece be $x$ feet.

Therefore, the length of longer beam is equal to $1+2x$

Evaluate:

Sum of lengths of longer and shorter pieces of beam is equal to the total length of beam. So,

$x+1+2x=16\\3x+1=16\\3x=16-1\\3x=15\\x=\frac{15}{3}=5$

Substitute and Solve:

Now, we have, $x=5$ .

Substitute 5 for $x$ for the lengths of shorter and longer pieces and solve for each. This gives,

Length of shorter piece = $x=5\textrm{ ft}$

Length of longer piece = $1+2x=1+2(5)=1+10=11\textrm{ ft}$

Therefore, the lengths of shorter and longer pieces are $5\textrm{ ft}$ and $11\textrm{ ft}$ respectively.

(4x + 3)(4x - 3) Help pls

tekilochka [14]

Answer:

$16x^2-9$

Step-by-step explanation:

$\left(4x+3\right)\left(4x-3\right)$

We´ll Apply Difference Two Squares Formula:

$\left(a+b\right)\left(a-b\right)=a^2-b^2$

$\longmapsto$ $\left(4x+3\right)\left(4x-3\right)$

$\longmapsto$ $\left(4x\right)^2-3^2$

Apply exponent rule:

$\left(a\times \:b\right)^n=a^nb^n$

$\longmapsto$ $4^2x^2-3^2$

$\longmapsto$ $16x^2-9$

Intervals are not my strongest suit when it comes to prepping for my act. I could use a little help, and advice if it isn’t too

Mashcka [7]

Answer:

F. (-4, oo)

Step-by-step explanation:

Start from the left side.

The arrow on the left side shows that the graph continues increasing forever as x decreases. Beginning at the highest value of y you see on the left side at point (-6, 5), as x increases, moving right along the x-axis, the y-values decrease. When you get to x = -4, y is at its lowest value which is 1.

Starting just to the right of x = -4, the y-values begin to increase from the lowest y-value of 1. The arrowhead at the right side top shows that the curve continues increasing forever to infinity.

The values of x for which y increases are all values greater than -4 and all the way to positive infinity.

This function is increasing for x > -4.

Now we need to write x > -4 in interval notation.

In interval notation, use a curved parenthesis to mean a number that is not included. The interval starts at -4, so it starts as

(-4

Then you write a comma to separate from the value where the interval ends.

(-4,

The interval in x of increasing values goes to positive infinity, so now you write the infinity symbol, and you close the interval with a curved parenthesis. By convention, infinity always gets a curved parenthesis. Also, I'll use oo for infinity below.

(-4, oo)
