Answer:
x = 1/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2 from both sides.
Step 3: Divide both sides by -4.
There are 1368 calories in 2 pounds of the ice cream.
Explanation:
342 per hlf lb so 2 lb’s is 4 times that, or 1368/2lb
Hope this helps!
If she did not reach her goal then
miles she drove must be less than 385
or
miles she drove<385
so rate=55 miles per hour
so
miles driven=h times 55
subsitute
55 times h<385
divide both sides by 55
h<7
she drove less than 7 hours
inequality=55h<385
h<7
Answer:
D - 43°
E - 43°
Step-by-step explanation:
In squares all sides are equal, which means one of these angles are given and neither one leave the square, so 43° would be the degree of each angle inside this square.

The area of the square in terms of x is 16x² - 8x + 1
Step-by-step explanation:
The formula of the area of a square is A = L², where L is the
length of its side
∵ The length of a side of a square is 4x - 1
∴ L = (4x - 1)
∵ The area of the square is A = L²
∴ A = (4x - 1)²
To solve bracket power 2
- Find (1st term)²
- Find (1st term × 2nd term × 2)
- Find (2nd term)²
- Add all the answers
The first term is 4x and the second term is -1
∵ (4x)² = 16x²
∵ (4x)(-1)(2) = -8x
∵ (-1)² = 1
∴ (4x -1)² = 16x² + -8x + 1
∴ (4x -1)² = 16x² - 8x + 1
∴ A = 16x² - 8x + 1
The area of the square in terms of x is 16x² - 8x + 1
