The trinomial that results from foiling the binomials is 6x^2+41x+30.
Answer:
173
Step-by-step explanation:
Q1
Divide each distance by its time to find the speed for each driver.
T: 380 km / 4 hr = 95 km/h
M: 530 km / 5 hr = 106 km/h
Martine's average speed was greater.
Q2
Bronze to aluminum is 25:2
The alloy is bronze plus aluminum, so by adding 25 + 2 you get 27.
Bronze to total is 25:27
25 is 27 as x is to 55
25/27 = x/55
27x = 25 * 55
x = 50.926
Answer: 50.926 kg of bronze
Q3
Manipulative toys to art toys is 30:40
Total toys = 30 + 40 = 70
manipulative toys are 30 out of 70
30/70 * 100 = 42.9%
The slope of a line that is perpendicular to a line whose equation is −2y = 3x + 7 is 
<em><u>Solution:</u></em>
Given that we have to find the slope of the line that is perpendicular to a line whose equation is −2y = 3x + 7
<em><u>The slope intercept form is given as:</u></em>
y = mx + c
Where "m" is the slope of line and "c" is the y - intercept
<em><u>Given equation is:</u></em>

On comparing the above equation with slope intercept form,

We know that product of slope of a line and slope of line perpendicular to it is -1
Therefore,

Thus slope of line that is perpendicular to given line is
