Answer:

Step-by-step explanation:

for 20 pounds of grass seed, we need 356 pounds of fertilizer

20 pounds of grass seed : 356 pounds of fertilizer

divide both sides by 20 to get 1 pound of grass seed on one side, as we want to figure out the corresponding amount of fertilizer for 1 pound of grass seed

20 pounds of grass seed/20 : 356 pounds of fertilizer/20

1 pound of grass seed: 17.8 pounds of fertilizer

Averi was trying to factor 4x2 + 20x - 16. She found

hichkok12 [17]

Answer:

The width will be $x^{2} +5x-4$

Step-by-step explanation:

Thinking process:

Let the model be:

$4x^{2} +20x-16$

factoring out 4 gives:

$4(x^{2} +5x-4)$

Factorizing the expression in the parentheses gives:

$4(x^{2} +5x-4)$

Therefore, since the expression in the parentheses cannot be factorized further, the expression is:

$length = 4 units\\width = x^{2} +5x-4$

A string is cut into two pieces in the ratio 2 : 7. The difference between the lengths of the two pieces is 90cm. Find the lengt

Nataly_w [17]

Answer:the length of the shorter string= 36cm

Step-by-step explanation:

Let us assume the lengths are 2x and 7x since thery are in the ratio of 2 :7

Such that Length of the shorter string = 2x

and the longer string = 7x so that the difference in Length which is 90cm can be expressed as

7x- 2x= 90

5x= 90

x 90/5

x= 18

shorter string = 2 x = 2x 18= 36cm

Longer strring = 7x 18=126cm
