Answer:
The width is 35 cm.
The length is 25 cm.
Step-by-step explanation:
Because the diameter is 47 cm
so the radius is 2x
r = 94 cm
A = πr² / 2
A = (3.14) (94)² / 2
A = 13872.52 cm²
A linear equation can be represented by:
y = mx + b
Where m = slope, and b = y intercept.
The slope is a rate of change, so our slope is $150.
The y intercept is the point where the equation crosses the y axis, or the "initial amount" in this case $500.
So our equation will be:
y = 150x + 500.
Multiplies to -0.72 = - 0.6 * (1.2).
Adds to 0.6 =
-0.6 + (1.2) = 1.2 - 0.6 = 0.6.
Hence the two numbers are -0.6 and 1.2.
Answer:
Step-by-step explanation:
All real numbers are solutions in both.
12(x2−x−1)+13(x2−x−1)=25(x2−x−1)
Step 1: Simplify both sides of the equation.
25x2−25x−25=25x2−25x−25
Step 2: Subtract 25x^2 from both sides.
25x2−25x−25−25x2=25x2−25x−25−25x2
−25x−25=−25x−25
Step 3: Add 25x to both sides.
−25x−25+25x=−25x−25+25x
−25=−25
Step 4: Add 25 to both sides.
−25+25=−25+25
0=0
