Answer:
L1 = 18 cm
W1 = 14 cm
A1 = 252 cm²
Step-by-step explanation:
Since the small rectangle is ½ the scale drawing of the original figure, therefore the dimensions of the smaller rectangle would be half of that of the original.
Thus:
Length (L) of the original = 36 cm
Length (L1) of the smaller rectangle = ½(36) = 18 cm
Width (W) of the original = 28 cm
Length (W1) of the smaller rectangle = ½(28) = 14 cm
Area (A1) of the smaller rectangle = L1 × W1 = 18 × 14 = 252 cm²
<span>f(x)=x^3-4x^2+2x+4, we know that f(2)=8-16+4+4=16-16=0
and we can write f(x)= (x-2)Q(x) so Q(x) = f(x) / (x-2)=x²-2x-2

finally the zeros are x=2, </span>x=1-sqrt3 or <span>x=1+sqrt3 </span>
Answer:

Step-by-step explanation:
Answer:
-9y^8
Step-by-step explanation:
-3y^4 * 3y^4
Multiply the coefficients
-3*3 = -9
Add the exponents since the base is the same
y^4 * y^4 = y^(4+4) = y^8
Put them back together
-9y^8
Answer:
26. t<-70 see description below.
Step-by-step explanation:
To solve an inequality in one variable, solve using inverse operations like any other equations. However, if dividing or multiplying by a negative at any points, flip the sign of the inequality.
Example:
-7 was multiplied to as an inverse operation to division by -7. Because it was negative, the inequality sign was flipped. To graph, plot -70 on the number line with an open circle. Then draw an arrow from -70 to the left.
