Answer:

A for a box, the surface area is given by:

6l², where l is the length of one side.

If the side is increased 10 times,

6(10l)²

=100 x6l²

The surface area increases 100 times. Thus, the new surface area is

272 * 100

= 27,200 sq in

What is (f - g)(x)? f(x) = 5x g(x) = 3x2 - 8x

erma4kov [3.2K]

Answer:

$(5x)-(3x^2-8x)=-3x^2+13x$

Step-by-step explanation:

$(f-g)(x)=f(x)-g(x)$

Using this, we can subtract and find the answer.

$(5x)-(3x^2-8x)=-3x^2+13x$

Ivan has 6 times as many blue beads as red beads. he has 49 red and blue beads in all. how many blue beads does Ivan have

salantis [7]

Let

x--------> the number of blue beads

y--------> the number of red beads

we know that

$x+y=49$

$x=49-y$ -------> equation $1$

$x=6y$ ------> equation $2$

equate equation $1$ and equation $2$

$49-y=6y\\ 6y+y=49\\ 7y=49\\\\ y=\frac{49}{7} \\ \\ y=7$

find the value of x

$x=6*7\\ x=42$

therefore

the answer is

Ivan has $42$ $blue beads$

Write the equation of the line in slope intercept form for the lone with a slope of 1/3 and a y intercept of (0,4)

Anastasy [175]

Answer:

$y=\frac{1}{3} x+4$

Step-by-step explanation:

Slope-intercept from is:

$y=mx+b$

m is the slope and b is the y-intercept. Insert slope:

$y=\frac{1}{3}x+b$

The y-intercept is at point (0,4). The y-intercept is when x equals 0, so take the value of y and insert into the equation:

$y=\frac{1}{3} x+4$

Finito.

If angle 2 = 48, determine the measure of angle 5.

Hatshy [7]

Answer:

Angle 2 = 48

we are going to divide 48 by 2 to get the Angle 1

Angle 1 = 24

then Angle 5 = (5×24)

Angle 5 = 120
