Here is the set up:

Solve for A in the equation AB + CD + EFG = Z.
Semenov [28]

Answer:

A =  (Z-CD - EFG)/B

Step-by-step explanation:

AB + CD + EFG = Z.

Subtract CD and EFG from each side

AB + CD + EFG-CD -EFG = Z-CD - EFG

AB  = Z-CD - EFG

Divide each side by B

AB /B = (Z-CD - EFG)/B

A =  (Z-CD - EFG)/B

A triangle has two sides of length 15 cm and 17 cm. Select all the values of its third side that would make it a right triangle
Natali [406]

Answer:

\sqrt{514} cm, 8cm, are both options

Step-by-step explanation:

For a right triangle one can find the length of the longest side by using the Pythagorean theorem. So there are two options I can think of that if the triangle is a right triangle will work. First remember what the Pythagorean theorem is : side a^2+side b^2=hypotenuse^2

The hypotenuse is the longest side of a right triangle. So if the sides that are 15 and 17 cm are not the longest sides then the formula would be:

15^{2} +17^2=c^2\\15^2+17^2=\sqrt{514}cm

But if 17cm is the longest side then:

a^2+15^2=17^2\\8^2+15^2=17^2\\a=8cm

Hope this helps!

The length of a rectangle is 4x + 5 and the width is 8x - 4. what is the perimtleter?
Luda [366]
Hi there!

Since the formula for finding the perimeter of a rectangle is length×2 + width × 2, we can follow this rule.

2 (4x + 5) + 2 (8x - 4)
= 8x + 10 + 16x - 8
= 24x + 2

So, the perimeter is 24x + 2.

Hope this helps!
