What is the value of the expression 2[4(2^3+5)]-4^2
ivolga24 [154]

Answer:

88

Step-by-step explanation:

Solve inside first

2^3=8

8+5= 13

Now multiply by 4

=52

Now by 2

=104

Now this is what we have left

=104-4^2

Make it easy by solving 4^2 which is 16.

104-16

=88

Please help me answer the question 9 though 10
olchik [2.2K]

Answer:

9) slope of AC = slope of FH

Equation of the line is y = - x + 5

10) Area = 320

Step-by-step explanation:

For 9, the only thing similar IS the slope of the hypotenuse because the triangles are along the same line. Unless they're asking for the equation of the line, then that's just using the point slope equation which is:

y = - x + 5

For 10, just multiply 4 and 5 by 4 to get 16 and 20. Then multiply 16 and 20 to get 320.

If storm has 3 bars she needs 22 bars but one bar equals 4 ores how many ores does she need?
oee [108]

Answer:

19 bars =<u> 76 more ores.</u>  22 bars = <u>88 total ores.</u>

Step-by-step explanation:

y = 4x

(4 times a number. Ex: x could be 98740757 or 2, it doesn't matter.)

1 b = 4 o

3 b = 12 o

22 - 3 = 19 b

19 b = 76 o (more)

22 b = 88 o (total)
