The total amount Ali biked was over two years. To find that amount, you add the amount he biked each year. Since he biked 261 miles in one year and c miles in the other, the total amount of miles is 261 + c. That would be the expression used to describe the total number of miles.
Correct question:
Evaluate and simplify the expression when a = 3 and b = 2,
given expression = 3b-2(1 - b)a - 2
Answer:
3b-2(1 - b)a - 2 at the given values is 10.
Step-by-step explanation:
Given;
3b-2(1 - b)a - 2
The expression is simplified as;
3b-2(1 - b) a - 2 = 3b - 2a(1 - b) - 2
= 3b - 2a + 2ab - 2
When a = 3 and b = 2; then, substitute these values in the simplified expression above;
3b - 2a + 2ab - 2 = 3(2) - 2(3) + 2(3 x 2) - 2
= 6 - 6 + 12 - 2
= 10
Therefore, 3b-2(1 - b)a - 2 at the given values is 10.
Answer:
please last option
using 45 degree as reference angle
using tan relation
Tan45=perpendicular /base
1 = x\6
x = 6
now using right angled triangle relation
H²=p²+b²
then h²= 6²+6²
H = √36+36
H =6√2
therefore y=6√2
Surface area of a cuboid
= [2(length)(width)] + [2(width)(height)] + [2(height)(length)]
= {[2(4)(2.5)] + [2(2.5)(2)] + [2(2)(4)]} units²
= (20 + 10 + 16) units²
= 46 units²
Answer: -3
Step by Step Explanation: This type of equation is called slope-intercept form, y=mx+b; the slope is m, so the slope is -3
