Answer:
3x^2+2x+8
Step-by-step explanation:
1. x^2+2x^2=3x^2
2. -3x+5x=2x
3.1+7=8
Answer:
irene spent $23.45
Step-by-step explanation:
Cost of gas = $3.50 per gallon = 350 cents
Quantity of gas = 6.7 gallons
Amount spent = Cost * Quantity
Amount = 350 * 6.7
Amount = 2345 cents
Amount = $23.45
(9×6/2) × 12 = 324

The easiest way to understand what you're doing is to find the area of the base first, then extend it upwards to find the volume using height. Hence the equation: b×h=v
So how do we find the base of a triange? Remember that every single triangle can be calculated as a square, then cut in half. So 9 × 6 / 2 = 27 cm2
The next step is to calculate the volume using the height of the figure. 27 × 12 = 324 cm3
**<em>remember to </em><em>use</em><em> </em><em>the</em><em> </em><em>correct</em><em> </em><em>units</em><em>,</em><em> </em><em>since</em><em> </em><em>area</em><em> </em><em>and</em><em> </em><em>volume</em><em> </em><em>are</em><em> </em><em>different</em><em>. </em>
Answer:
10y = 13x + 139
Step-by-step explanation:
Points (-5, -3) and (-15, -16) are the two points through which Line 1 passes.
So, the slope of the line 1 is 
Now, the slope of the parallel straight line i.e. line 2 will be same as line 1 i.e. 
Let us assume that the equation of line 2 is
{Where c is a constant} ....... (1)
Now, line 2 passes through the point (-13, 17). Hence, this point will satisfy equation (1).
So, 
⇒ 
Therefore, the equation of line 2 will be
⇒ 10y = 13x + 139 (Answer)
