A = 1/2 h (a+b)
A / 1/2 h = a + b
A / 1/2 h - b = a

a = A / 1/2 h - b

Hope this helps

Answer:

√27

Step-by-step explanation:

The triangles of the pyramid are equilateral triangles with sides of 6''.

Dividing a triangle into two equal parts we get two congruent right triangles, with a hypotenuse of 6'', one leg of 3'', and the other leg is the slant height (s). From Pythagorean theorem:

3² + s² = 6²

s² = 6² - 3²

s = √27

Answer the questions below about Line 1 and Line 2 shown below.

givi [52]

The expression was rewritten using the commutative law of addition.
Line 1 says 3 + 4, which could be represented using dots as ••• + •••• for a total of 7 dots.
Line 2 says 4 + 3, which could be represented using dots as •••• + ••• for a total of 7 dots.

<h3>What is the commutative law of addition?</h3>

The commutative law of addition is also referred to as the law of cumulative addition and it states that if two numbers are added together, then, the outcome is equal to the addition of their interchanged position because addition is considered as a binary operation.

This ultimately implies that, the sum of addends would always be the same (equal) regardless of their arrangement in accordance with the commutative law of addition. Mathematically, the commutative law of addition can be represented using the following formula:

A + B = B + A.

In this context, we can reasonably infer and logically deduce that the given expression was rewritten using the commutative law of addition.

In conclusion, Line 1 says 3 + 4, which could be represented using dots as ••• + •••• for a total of 7 dots. Line 2 says 4 + 3, which could be represented using dots as •••• + ••• for a total of 7 dots.

pleaseee help how do i write an equation in slope-intercept form for the line with slope 1/3 and y-intercept -3?

Montano1993 [528]

Answer:

y=1/3x -3

Step-by-step explanation:

Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept, or the y-value at which the line intersects the y-axis.

Your slope is 1/3, and your y-int. is -3, so substitute those values in:

y=1/3(x) - 3
