Answer:
<u>Volume</u><u>:</u> 1135.82 yd³
<u>Surface Area</u><u>:</u> 657.12 yd²
Step-by-step explanation:
V = whl
12.2 · 9.8 · 9.5
1135.82
A = 2(wl + hl + hw)
2 · (12.2 · 9.5 + 9.8 · 9.5 + 9.8 · 12.2)
657.12
Answer:
The numbers are
22 and 23 to solve a problem like this, we need to read and define as we go. Let me explain. So we know that there are two consecutive integers. They can be
x and x+1
. Since their consecutive, one has to be 1
number higher (or lower) than the other. Ok, so first we need "seven times the larger"( 7x+1)
Next, we need to "minus three times the smaller" 7(x+1)−3x
Is equal to " 957(x+1)−3x=95
Alright! There's the equation, now we just need to solve for x! First we are going to get everything on one side and distribute the 7=7x+7−3x−95=4x−88
Pull out a
=4(x−22)Now that we have two terms, we can set them both equal to
0 and solve.4≠0
This can never be true, lets move to the next term (x−22)=0x=
22 That's it! So your two consecutive numbers are
22
Answer:
( x+3 )² = 7
expand ( x+3 )² : x²+6x+9
x²+6x+9=7
x²+6x+2=0
use a scientific calculator casio mode setup click no 5 , then click 3 input the equation
a = 1
b = 6
c = 2
answer : x = -3+square root 7 or x = -3-square root 7
