Answer:
Number of sweets =54
Step-by-step explanation:
Let number of friends = x
Number of sweets = y
Glenda gives 6 to each of her friend,
6x = y ----------------(I)
If she gives each of them 4, 18 is left
4x + 18 = y ---------------(II)
From (I)& (II)
6x = 4x + 18
Subtract 4x from both sides
6x - 4x = 4x + 18 - 4x
2x = 18
Divide both sides by 2
2x/2 = 18/2
x = 9
y = 6x
= 6 * 9
y = 54
Number of sweets =54
Answer:
24 ft²
6 × 3 + (½ × 4 × 3)
Step-by-step explanation:
Split shape into a rectangle and triangle;
The rectangle is 6 by 3 ft, the area can be found by multiplying the 2 dimensions:
6 × 3 = 18
The triangle has base 4 ft, the total length of the shape (10 ft) take the 6 ft that is part of the rectangle;
The height is 3 ft;
The area us found by ½ × base × height:
½ × 4 × 3 = 6
Add this together to get the total area.

Answer:
4:00 pm
Step-by-step explanation:
To find the time it takes Malik to finish his English essay, let's start by subtracting one hour.
5:30 minus 1 hour is 4:30.
Now, subtract 30 minutes.
4:30 minus 30 minutes is 4:00.
Malik started working on his English essay at 4:00 pm.
Hope that helps.
2x^2+20x = -38
2x^2 + 20x + 38 = 0
Divide both sides by 2.
x^2 + 10x + 19 = 0
The quadratic formula works very well here.
Let a = 1, b = 10 and c = 19
x = [-b +- sqrt{b^2 - 4ac}]/(2a)
Plug those values into the formula to find two answers for x.
One is negative and the other positive.
Good luck.
