Step-by-step explanation:
7.45 subtract 3.00 is 4.45
aka
7.00 subtract 3.00 which is 4.00 and add the 0.45
Answer:
(x + 3)(x - 5)
Step-by-step explanation:
Well to factor x^2-2x-15,
we need to find 2 numbers that multiply to get -15 and add to get -2.
3*-5 = -15
3x + -5x = -2x
x*x = x^2
Factored (x + 3)(x - 5)

Mr. Cutler should make 2 bricks and 7 tiles to maximize his profit.
<u>Step-by-step explanation:</u>
Let the no. of bricks be 'b'
Let the no. of tiles be 't'
Time taken for 1 brick = 10 mins
Time taken for 1 tile = 20 mins
Clay used for 1 bick = 3 pounds
Clay used for 1 tile = 2 pounds
Profit on each brick = $2
Profit on each tile = $3
Total time available= 160 mins
Total clay available = 20 pounds
10b + 20t = 160
b + 2t = 16
b = 16 - 2t
3b + 2t = 20
3(16 - 2t) +2t = 20
48 - 6t + 2t = 20
48 - 4t = 20
-4t = 20-48
4t = 28
t = 7
b = 16 - 2t
b = 16 - 14
b = 2
Mr. Cutler should make 2 bricks and 7 tiles to maximize his profit.
Answer:
312cm2
Step-by-step explanation:
Area of the triangles:
A =1/2bh
A=1/2(10*12) = 1/2*120=60.
There are two triangles. 60*2=120. 120 is the area of both triangles.
Area of the rectangle:
16*12=192.
120+192=312cm2
