1+4(2x - 3)-x
Mutiply the bracket by 4
1+ (4)(2x)(4)(-3)-x
1+8x-12-x
8x-x+1-12 just rearranging
7x-11
Answer : D. 7x - 11
Answer:
A. 7.2 centimeters
Step-by-step explanation:
The length of the base is 7.2 centimeters. The area of a rectangle is length*width
The length is unknown but the area is known. To find the length, all we have to do is divide the area from the height.
The working is as follows :
Area = 90 cm²
Height = 12.5 cm
Length = ?
<em>Length</em><em> </em><em>=</em><em> </em><em>Area</em><em> </em><em>÷</em><em> </em><em>Height</em>
<em>=</em><em> </em><em>90</em><em> </em><em>÷</em><em> </em><em>12</em><em>.</em><em>5</em>
<em>=</em><em> </em><em>7.2cm</em>
Answer

Step-by-step explanation:
Answer:
C. a = 7
D. c = -3
Step-by-step explanation:
C. 7(2a + 3) + 21 = 100+ 40
14a + 21 + 21 = 140
14a = 140 - 21 - 21
14a = 98
a = 7
D. 6+ 14 - 12c = 56
20 - 12c = 56
-12c = 56 - 20
-12c = 36
c = - 3
