You get area when you multiply the 2 sides together
the sides are 8ft and (2+x)ft
when you multiply them together, it looks like
8(2+x) ft^2
so distribute the 8

You get perimeter when you add up all the sides together
the sides 8 and (2+x) are given, but remember the opposite sides are also 8 and (2+x)
when you add up all the sides, you get

8+(2+x)+8+(2+x)

Last one help. Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole

Fed [463]

The formula for finding the lateral area for a triangular prism is
$A_{L} = (a + b + c )h$

So put in the values and you get

$A_{L} = (12.04 + 9 + 8 )23$
$A_{L} = 668$

The formula for finding the surface area of a triangular prism is
SA = bh + (s1 + s2 + s3)H

So put in all the values and you get

SA = 9(8) + (9 + 8 + 12.04)23
SA = 740

Hope this helps! :)

The formula F=9/5C+32 converts temperatures from Celsius C to Fahrenheit F. A. Solve the formula for C b. The boiling point of w

liraira [26]

Answer:

(a) $\therefore C=\frac59(F-32)$

(b)The boiling point of water in Celsius scale is 100°C.

(c)The setting in Celsius scale is 26.7°C.

Step-by-step explanation:

Given that,the formula is

$F=\frac95 C+32$ ......(1)

(a)

Given that,

$F=\frac95 C+32$

$\Rightarrow F-32=\frac95 C+32-32$ [ subtracting 32 from both sides]

$\Rightarrow F-32=\frac95 C$

$\Rightarrow \frac95 C=F-32$

$\Rightarrow C=\frac59(F-32)$ ......(2) [Multiplying $\frac59$ ]

$\therefore C=\frac59(F-32)$

(b)

Given that, the boiling point of water is 212°F.

Putting F=212 in equation (2)

$\therefore C=\frac59(212-32)$

$\Rightarrow C=\frac59\times 180$

$\Rightarrow C=5\times 20$

$\Rightarrow C=100$

The boiling point of water is 100°C.

(c)

Given that, a house thermostat is set at 80 degree.

Putting F=80 in equation (2)

$\therefore C=\frac59(80-32)$

$\Rightarrow C=\frac59\times 48$

$\Rightarrow C\approx26.7$

The setting in Celsius scale is 26.7°C.
