X + 3 • ( 10 + y ) - 7x - 4
x + 30 + 3y - 7x - y
x - 7x + 3y - y + 30
-6x + 2y + 30
1) 8x-13
2)19r-19s
3)8m-10n
Solve in the parentheses then label the ones with the same variable and solve those setting up the equation with variable first. Do check this I am not perfect.
Hope this helped! ;)
Answer:
71
Step-by-step explanation:
Area of fig 1 = 1 x b = 7 x 4 = 28
Area of fig 2 = l x b = (7-2) x 3 = 5 x 3 = 15
Area of fig 1 = 1 x b = 7 x 4 = 28 (same as ig 1)
Area of whole fig = fig 1 + fig 2 + fig 3 = 28+15+28 = 71
I hope im right !!
Answer:
Step-by-step explanation:
2√54+5√24
2 * sqrt(9*6) + 5*sqrt(4*6)
2*sqrt(9) *sqrt(6) + 5*sqrt(4) * sqrt(6)
2*3 sqrt(6) + 5*2 sqrt(6)
6sqrt(6)+10sqrt(6)
16sqrt(6)
