Pretty sure x is 4 in #9
FG is congruent to ED, and GD and FE are parallel, so that means
16x + 1 = 65
Subtract 1 on both sides you get
16x = 64
Divide by 16 on both sides
x = 4
3a+2.25=3a+1.75
Implies 3a+2.25=3a+1.75+.5
Answer is 0.5
Answer:
equation of the line: 2x - y = 1
Step-by-step explanation:
Given coordinates: (2, 3) and (3,5)
find slope of the equation:
using the formula:
→ 
→
.............this is slope, also refereed as (m) in short form.
using the equation formula:
using the formula:
→ y - 3 = 2 ( x - 2 )
→ y - 3 = 2x - 4
→ y = 2x -4 +3
→ y = 2x - 1
→ -2x + y = -1
→ (-2x + y)/-1 = -1 /-1 [ divide both sides by -1 ]
→ 2x - y = 1 .......final answer in standard form where ( Ax + By = C ) where "A" should be positive and "C" constant on the right hand side.
Answer:
s = 21 cm
Step-by-step explanation:
Square is s x s = area
So you just take the square root button of the calculator to find that 21 x 21 is 441.
First divide 12 by 3
then we have 2x-4=7
add 4 to both sides to get 2x=12
divide both sides by 2 to get x=6
