Answer:

x =5

Step-by-step explanation:

We can use ratios for the side lengths

9              x

--------- = -----------

9+18       x+10

Using cross products

9 (x+10) = x * (9+18)

Distribute

9x+90 = x*27

9x+90 = 27x

Subtract 9x from each side

9x-9x+90 = 27x-9x

90 = 18x

Divide each side by 18

90/18 = 18x/18

5 =x

Write an equivalent expression for 7¹² × 7⁴
ira [324]

Answer:

\huge\boxed{7^{16}}

Step-by-step explanation:

We can use exponent rules to try and simplify this expression down.

Exponent rules tell us that x^a + x^b = x^{a+b}.

This means that since we have the same base on both terms (7 and 7), we can add the exponents to get a simplified expression.

12 + 4 = 16

So our simplified expression is 7^{16}.

Hope this helped!

Look at the graph shown<br> Which equation best represents the line?
Brilliant_brown [7]

y=\frac{11}{4}x +4 is the equation best represents the line.

Solution:

Take any two points on the line.

Let the points be (0, –4) and (4, 7).

x_1=0,y_1=-4,x_2=4, y_2=7

General form of equation of a line is y = mx + c

where m is the slope and c is the y-intercept of the line.

<em>y-intercept is the point which line crosses at y-axis.</em>

In the given line, y-intercept is 4.

c = 4

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{7-(-4)}{4-0}

$m=\frac{11}{4}

Equation of the line:

y = mx + c

y=\frac{11}{4}x +4

Hence y=\frac{11}{4}x +4 is the equation best represents the line.

For the following figure what’s the value of x?
Leto [7]

Answer:

x = 8 in

y = 8sqrt(2) in

Step-by-step explanation:

x = 8

AC = BC

Because opposite angles are equal.

8² + 8² = hyp²

hyp² = 64 + 64 = 128

hyp = sqrt(128)

hyp = 8sqrt(2)

Where sqrt is the square root
