The area is the length times the width. Find area of shapes by counting unit squares. Some shapes will require combining partial square units to find area.<span>
For example - </span><span>A rectangle is 5 centimeters long and 4 centimeters wide. What is its area? </span>
Area = Length * width
The length is <span><span>5</span></span> centimeters. The width is <span><span>4</span></span> centimeters. So the area is <span><span>5 times </span>4</span> square centimeters.
= 20 square centimeters
Step-by-step explanation:

4x² - 12x = 7
- 7 - 7
4x² - 12x - 7 = 0
4x² + 2x - 14x - 7 = 0
2x(2x) + 2x(1) - 7(2x) - 7(1) = 0
2x(2x + 1) - 7(2x + 1) = 0
(2x - 7)(2x + 1) = 0
2x - 7 = 0 or 2x + 1 = 0
+ 7 + 7 - 1 - 1
2x = 7 2x = -1
2 2 2 2
x = 3¹/₂ or x = ⁻¹/₂
34 and 38 are both multiples of 34 and 38 so divide each by 2
34/38 = 17/19
this is its simplest form as it cannot be cancelled down any more
Answer:
-14 - 12i
Step-by-step explanation:
Apply complex arithmetic rule: (ai)(b + ci) = -ac + abi
a = 2, b = 6, c = -7
-( -2(-7) + 2*6i )
-( 14 + 12i)
-14 - 12i
