The length of a rectangle is four times its width.
If the perimeter of the rectangle is 70 ft, find its length and width.
Answers
Let W represent width of rectangle
L=4W
2L+2W=70
Substitute 4W for L
2(4W)+2W=70
8W+2W=70
10W=70
Divide both sides by 10
W=7
Use equation from beginning
L=4(7)
L=28
Width is 7 ft, length is 28 ft
Check work
2(28)+2(7)=70
56+14=70
70=70

i need help, can someone show me how to solve it
Answers
Answer:
9
Step-by-step explanation:
Simply plug -3 in for x.
-2(-3)^2-7(-3)+6
(-3)^2=9
9*-2= -18
-7*-3=21
-18+21=3
3+6=9
Answer:
f(-3) = 9
Step-by-step explanation:
Here we have a quadratic function in x: and we want to know the value of this function when x = -3.
Substituting -3 for x in f(x) = -2x^2 - 7x + 6, we get f(-3) = -2(-3)^2 - 7(-3) + 6, which works out to f(-3) = -2(9) + 21 + 6, or
f(-3) = -18 + 27 = 9
Thus, f(-3) = 9

if a quadratic equation with real coefficients has a discriminant of -2, then its roots must be
A:2 real
B:1 real
C: imaginary
D:equal
Answers
When the discriminant is negative, this implies that the quadratic equation has no roots (or zeros) in the set of real numbers. The roots belong to the set of complex numbers, and will be called "complex roots" (or "imaginary roots").
Therefore, the correct answer is C: imaginary.

the ratio of 3 numbers is 2:3:4. If the sum of the numbers is 108, find the numbers. NEED ANSWERS ASAP
Answers
Step-by-step explanation:
x + y + z = 108
x/y = 2/3
y/z = 3/4
x = 2y/3
z = 4y/3
we use these 2 as substitute in the first equation
2y/3 + y + 4y/3 = 108
2y + 3y + 4y = 324
9y = 324
y = 36
x = 2y/3 = 2×36/3 = 2×12 = 24
z = 4y/3 = 4×36/3 = 4×12 = 48
