Ryan square pyramid
</span>[Base Area]=10*10=100 feet²
<span>Perimeter=10+10+10+10=40 feet
</span>[Slant Length]=12 feet
Surface Area=100+12*40*12=5860 feet²
Scott square pyramid  
[Base Area]=12*12=144 feet²
Perimeter=12+12+12+12=48 feet
[Slant Length]=10 feet
Surface Area=144+12*48*10=5904 feet²

A rectangular mural has dimensions of (x + 10) and (x + 3) feet. If the area of the mural is 60
Crank

Answer:

Dimensions are 12 , 5

Step-by-step explanation:

Area of rectangular mural = length * width

length * width = 60 square feet

(x + 10)(x + 3) = 60

Use FOIL method

x*x + x*3 + 10*x + 10*3 = 60

x² + <u>3x + 10x</u> + 30 = 60      {Combine like terms}

x² +<u> 13x</u> + 30 - 60 = 0

x² + 13x - 30 = 0

Sum = 13

Product = -30

Factors =  15 , -2     (15+ (-2) = 13 ; 15*(-2) = -30)

x² + 15x - 2x - 30 =0  {Rewrite middle terms}

x(x + 15) - 2(x + 15) = 0

(x + 15)(x - 2) =0

x - 2 = 0             {Ignore (x +15) as dimensions wont have a negative value}

x = 2

x + 10 = 2 + 10 = 12

x + 3 = 2 + 3 = 5

Dimensions are 12 , 5
