Answer:
Add 1 to each side
Multiply each side by 4
Take the square root of each side
Subtract 5 from each side
Combine terms
Step-by-step explanation:
1/4(x+5)^2-1=3
Add 1 to each side
1/4(x+5)^2-1+1=3+1
1/4(x+5)^2=4
Multiply each side by 4
4*1/4(x+5)^2=4*4
(x+5)^2=16
Take the square root of each side
sqrt((x+5)^2)=±sqrt(16)
x+5 = ±4
Subtract 5 from each side
x+5-5 = -5 ±4
x = -5 ±4
Combine terms
x = -5+4 x = -5-4
x = -1 x = -9

<u><em>He spent £25 on the first day.</em></u>
- We are told he had spent £28 over 7 days.
Each day, he spends 50 pence more than the previous day. This means that;
1 pound = 100 pence
Thus, 50 pence = (50 × 1)/100 = £0.5
- If the money he spent on the first day is £x.
- On second day, he would have spent a total of; £(x + 0.5)
- On third day; x + 0.5 + 0.5= x + 1
- On fourth day; x + 1 + 0.5 = x + 1.5
- On fifth day; x + 1.5 + 0.5 = x + 2
- On sixth day; x + 2 + 0.5 = x + 2.5
- On seventh day; x + 2.5 + 0.5 = x + 3
x = 28 - 3
x = £25

Answer:
-2,-6,-18
Step-by-step explanation:
let g1,g2,g3 be three G.M.s between -2/3 and -54
now -2/3,g1,g2,g3,-54 are geometric
n=5
an=a1 r^{n-1}
-54=-2/3 r^{5-1}
r^{4}=-54×-3/2=81=3^4
r=3
g1=a1×r=-2/3×3=-2
g2=a1×r²=-2/3×3²=-6
g3=a1×r³=-2/3×3³=-18
