Step-by-step explanation:
1) = {5(x+y)} - 2x
= 5x + 5y - 2x
= 3x + 5y
2)= {2(p×q)} + (p×q)
= (2p×2q)+ p×q
= 4pq + pq
= 5pq
3)= 6a + (8b + 2a)
= 8a + 8b
= 8(a+b)
4)= 3x² + ( x²+7x)
= 4x² + 7x
= x(4x+7)

Answer:
y = 4/3x -7
Step-by-step explanation:
The marked points differ in their y-values by +4, and their x-values by 3. The slope of the line is ...
m = rise/run = 4/3
There is a marked point on the y-axis at y = -7. This is the y-intercept. Then the desired equation is ...
y = mx +b . . . . . line with slope m and y-intercept b
y = 4/3x -7
16.3%=0.163
353(0.163)=57.539
57.539 is rounded to 57.5
There are 57.5 millimeters of acid. Hope this helps!
The rectangle is 6·5 which is 30. The triangle is a little harder but just has one extra step. The length is 6 and the height shown is 2. The figure is only half of a rectangle though because it's a triangle, so you divide by 2. Six times two= 12. Divided by 2 equals 6. Now add to find the total. 30+6= 36 units squared.
