F(x)=x^2+3x+5
f(3+h)=(3+h)^2+3(3+h)+5
f(3+h)=9+6h+h^2+9+3h+5
f(3+h)=23+9h+h^2
It is c because I had this question on the test
Area of rectangle is
Step-by-step explanation:
Given,
Width of rectangle = m cm
As length is 5 times more than width;
Length of rectangle = 5m cm

Answer:
W is less than or equal to 2200
Step-by-step explanation:
(I don't know how to do the less than or equal to symbol on the computer)
<span>-7x + 8y = -9
8y = 7x - 9
y = 7/8x - 9/8
so line </span><span>-7x+8y=-9 has slope = 7/8
</span><span>perpendicular lines, slope will be opposite and reciprocal
so new line has slope = -8/7
passing thru </span><span>(2,-5)
</span>y = mx + b
-5 = -8/7(2) + b
-5 = -16/7 + b
b = -5 + 16/7
b = -35/7 + 16/7
b = -19/7
equation
y = -8/7x - 19/7
hope it helps
