Answer:

To find the height of a cube you simply need to know the length of the sides of a cube.

Step-by-step explanation:

All sides of a cube are equal because it is made up of squares. If a cube has a length of 3 cm, then it will also have a height of 3 cm.

svet-max [94.6K]

1 Subtract 22 from both sides
13x=4x+38-213x=4x+38−2

2 Simplify 4x+38-24x+38−2 to 4x+364x+36
13x=4x+3613x=4x+36

3 Subtract 4x4x from both sides
13x-4x=3613x−4x=36

4 Simplify 13x-4x13x−4x to 9x9x
9x=369x=36

5 Divide both sides by 99
x=\frac{36}{9}x=
9

36

6 Simplify \frac{36}{9}
9

36
to 44
x=4x=4

One market sells a 3 kilogram bag of tortillas for 42 pesos and another sells 2 kilograms of tortillas for 26 pesos which unit p

Dafna1 [17]

Answer:

2 kilogram bag.

Step-by-step explanation:

To figure this out, we need to divide the price by the amount of kilograms. Lets start with the 3 kilo bag. Divide 42 by 3, let y equal the price per kilo

42/3=y

Divide

14=y

Now lets do the same with the 2 kilo bag. Divide 26 by 2. Let x be this number.

26/2=x

divide

13=x

The 2 kilo bag is better as its 13 pesos per kilo compared to the 3 kilo bag's 14 pesos per kilogram.

If xsquared+ysquared=57 , xy=3 . find the value of 3(x+y)squared

shepuryov [24]

Answer:

189

Step-by-step explanation:

If you mean this, my answer is 3x63= 189

${x}^{2} + {y}^{2} = 57 \\ xy = 3$

${x}^{2} + {y}^{2} + 2xy = 57 + 2 \times 3$

${(x + y)}^{2} = 63$

$3 {(x + y)}^{2} = 3 \times 63 = 189$

In rectangle MNPQ with side MN = 16 in, point L is the midpoint of PQ and m∠QLM = 45°. Find the perimeter of the rectangle.

Marina86 [1]

See the attached figure

we know that
MN=16 in-------------> PQ=MN
PQ=16 in
<span>L is the midpoint of PQ-----------> distance QL=</span><span>PQ/2
QL=8 in
if </span>m∠QLM = 45°
then
MQ=QL
MQ=8 in

Perimeter=[MN]*2+[MQ]*2=16*2+8*2=48 in

the answer is 48 in
