Hey there :)
27x² is what we are trying to factorise
When factorising, we do not add but we multiply
Jude factored : ( 20x )( 7x ) → This is wrong, since 20x × 7x = 140x²
Yasmin factored : ( 9 )( 3x² ) → This is right indeed as 9 × 3x² = 27x²
Yasmin is right
Consider triangle WBG, where points W, B and G represent Weather Station, Balloon and Ground, respectively. This triangle is right with right angle at vertex G. The legs of this triangle are GB and GW, the hypotenuse is BW.
From the question you know that GB=4 km and GW=1 km. By the Pythagorean theorem,

Answer: nearly 4.123 km
Answer:
-19
Step-by-step explanation:
substitude d for 5:
-3(5)-4
= -15-4
= -19
I think you mean volume.
V=8
The feeders in battling machine are represented in proportions and fractions.
- The equation that represents the problem is:

- The feeder can hold <em>30 baseballs</em>, when full
The given parameters are:
<em />
<em> ------ 1/6 full</em>
<em />
<em> --- baseballs added</em>
<em />
<em> ---- 2/3 full</em>
<em />
So, the equation that represents the problem is:

So, we have:

The number of baseballs it can hold is calculated as follows:

Multiply through by 6

Collect like terms


Divide through by 3

Hence, the feeder can hold 30 baseballs, when full
