The pythagorean theorem says that a² + b² = c²

You're given the b and the c so substitute the values in: a² + 12² = 15²

a² + 144 = 225; subtract 144 from both sides

a² = 81; square root each side

a = 9, or choice C

Answer:

A = 3x³ - 22x² + 30x - 36

Step-by-step explanation:

Area of a Rectangle: A = lw

Step 1: Define

l = 3x² - 4x + 6

w = x - 6

Step 2: Substitute and Evaluate

A = (3x² - 4x + 6)(x - 6)

A = 3x³ - 4x² + 6x - 18x² + 24x - 36

A = 3x³ - 22x² + 30x - 36

A candy store makes a 13–pound mixture of gummy bears, jelly beans, and gobstoppers. The cost of gummy bears is $1.00 per pound,
bulgar [2K]
X = gummy bears, y = jelly beans, z = gobstoppers
x + y + z = 13
x + 2y + 2z = 20
x = 3y

3y + y + z = 13
4y + z = 13

3y + 2y + 2z = 20
5y + 2z = 20

4y + z = 13....multiply by -2
5y + 2z = 20
-----------------
-8y - 2z = -26
5y + 2z = 20
---------------add
-3y = -6
y = 2........2 lbs jelly beans

x = 3y
x = 3(2)
x = 6....6 lbs gummy bears

x + y + z = 13
6 + 2 + z = 13
8 + z = 13
z = 13 - 8
z = 5........5 lbs gobstoppers

so we have : 6 lbs gummy bears (x), 2 lbs jelly beans (y), and 5 lbs gobstoppers (z)

Sheila has 12 1/2 pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 2 1/4 pounds
NeX [460]

Answer:

6 containers needed

Step-by-step explanation:

Given

Total = 12\frac{1}{2}\ lb ----- Size

Container = 2\frac{1}{4}\ lb ----- Size

Required

Determine the number of containers needed

This question illustrates the knowledge of fraction and division.

To get the number of containers needed, we simply divide the total size by the size of the container as follows;

Number = Total/Container

Number = 12\frac{1}{2}/2\frac{1}{4}

Convert to improper fractions

Number = \frac{25}{2}/\frac{9}{4}

Number = \frac{25}{2}*\frac{4}{9}

Number = \frac{100}{18}

Number = 5.5555556

Number = 6 --- Approximated

ABCD is a parallelogram angle a is equal to (5x-2) and angle c is equal to 48 find x
bulgar [2K]
For a parallelogram, we know that there are to pairs of angles that are the same and that all 4 angles add to 360.

2(5x-2)+2(48)=360
2(5x-2)+96=360
10x-4+96=360
10x+92=360
10x=268
x=26.8

Final answer: x=26.8

Hope this helps!
