Hello pls help! i’m very confused
sesenic [268]

Answer:

<h2>9</h2>

Step-by-step explanation:

9 1/3 is 9.333333333 but you only need the 9.333. So you look at the 3 after the nine. 4 or below goes to the number lower and 5 or higher goes to the number higher. So in this case 9.3 the 3 is smaller than 4 so therefore the number is smaller so it stays nine.

║║║║The length of a rectangle is 5 inches more than its width, x. The area of a rectangle can be represented by the equation x 2
lbvjy [14]
So given l = x+5 and w = x

area represented by equation x^2 +5x = 300

x^2 +5x -300 =0

(x+20)(x-15)=0

x+20 =0
x = -20

x-15=0
x=15

so from these result the width of rectangle equal 15 inches and the length of rectangle equal 20 inches

A triangle has a base of 4 units and a height of 3 units. Mark draws the triangle again but doubles the height. How does the are
dexar [7]

Answer:

The area increases by 6 square units.

Step-by-step explanation:

The formula for the area of a triangle is base times height divided by two.

So, first solve 3 times 4 divided by 2.

Simplify 4 and 2 and you get 3 times 2 which = 6

Then Mark doubles it right?

So do 6 times 2 and you get 12

The first answer is 6, so it increased by 6.

I hope this answer helped. Sorry if I was wrong.
