Answer:
Option A
Step-by-step explanation:
When any triangle is dilated from the pre-image, its sides will never be congruent to the pre-image. However, its angles will be congruent and the triangles will be similar.
Find what that area is
22*66=1452
5 times of that is
1452*5=7260
s=seconds
(22+33s)(66+33s)=7260
1089s^2+2904s+1452=7260
minus 7260 from both sides
1089s^2+2904s-5808=0
factor or use quadratic formula
(363)(x+4)(3x-4)=0
set each to zero
x+4=0
x=-4, false, it is increasing, not decreasing
3x-4=0
3x=4
x=4/3
answer is 4/3 seconds
Answer:
The number is 0
Step-by-step explanation:
We form an equation using the statement:
8 = 7x + 8
Then we solve it:
8 = 7x + 8
8 - 8 = 7x
0 = 7x
0 ÷ 7 = x
x = 0
He deposited a total of $180.
Wrote two checks that totaled $80
x=180-80
180-80=100
Therefore, he would have $100 in his checking account after the two checks.
Answer:
l = 14 , w = 12
Step-by-step explanation:
2l + 2w = 52 → (1)
l - w = 2 → (2)
multiplying (2) by 2 and adding to (1) will eliminate the w- term
2l - 2w = 4 → (3)
add (1) and (3) term by term to eliminate w
4l + 0 = 56
4l = 56 ( divide both sides by 4 )
l = 14
substitute l 14 into either of the 2 equations and solve for w
substituting into (1)
2(14) + 2w = 52
28 + 2w = 52 ( subtract 28 from both sides )
2w = 24 ( divide both sides by 2 )
w = 12
