The length of a rectangle is 8 feet longer than the width. If the perimeter is 80 feet, find the length and width of the rectang
Klio2033 [76]

perimeter = 2L + 2W

 L=8+w

perimeter = 2(8+w) +2w

80 =16+2w+2w

80 = 16 +4w

64 =4w

w=64/4 = 16

 l=16+8 =24

 length = 24 feet

width = 16 feet


 check 2(24) +2(16) = 48 + 32 = 80

Rewrite the equation 4x + 5x2 = 8x – 7 in standard form and
Makovka662 [10]

Answer:

The correct option is a=5, b = -4, c=7 ....

Step-by-step explanation:

The standard form is ax²+bx+c=0

where a, b, and c being constants, or numerical coefficients, and x is an unknown variable.

The given expression is:

4x + 5x2 = 8x – 7

To make it a standard equation we will move all the values to the left hand side and 0 will be left at the right hand side.

4x+5x²-8x+7=0

Now solve the like terms and arrange the equation according to the standard form:

ax²+bx+c=0

5x² - 4x +7 =0

Here a = 5

b = -4

c= 7

Thus the correct option is a=5, b = -4, c=7 ....

jeka94

Answer:

1/10x * 1/10x

Step-by-step explanation:

Writing a term with negative exponents is the same as putting it in a fraction.

10x^-1 = 1/10x

so the expression would be

1/10x * 1/10x
