Answer:
Step-by-step explanation:
2.5 x 
* 3.7 x 
add the expoents, and multiply the coefficients
2.5 * 3.7 =9.25
= 
9.25 x
Answer:
what?? the question is not clear.....
Answer:
18cm
Step-by-step explanation:
Area of Trapezium = 1/2(a + b) h
Where:
A = 352cm^2
h = distance between parallel sides = 16cm
a = 25cm
b = ?
352 = 1/2 (25 + b) 16
352 = (25 + b) 8
352 = 200 + 8b
352 - 200 = 8b
152 = 8b
152/8 = b
19= b
→b = 19cm
The other parallel side is 19cm.
Answer:
Simplifying
2x + -15 + x + -5 = 148
Reorder the terms:
-15 + -5 + 2x + x = 148
Combine like terms: -15 + -5 = -20
-20 + 2x + x = 148
Combine like terms: 2x + x = 3x
-20 + 3x = 148
Solving
-20 + 3x = 148
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '20' to each side of the equation.
-20 + 20 + 3x = 148 + 20
Combine like terms: -20 + 20 = 0
0 + 3x = 148 + 20
3x = 148 + 20
Combine like terms: 148 + 20 = 168
3x = 168
Divide each side by '3'.
x = 56
Simplifying
x = 56
