Answer:
14*7=98 (Original area)
28*14=392 (New area)
The area of the new one is 4 times the original, since the width and length wee doubled.
28 is the doubled amount of 14. 14 is the doubled amount of 7.
Please but brainliest if you can.
Can you add space bars?I really cant work it out without space bars.
Answer:
1) 18
2) 30
3) 6
4) 3000
5) 5
Explanation:
1
25+15+20=60
x/60 = 60/100
x/60 = 3/5
x= 60(3/5)
x=36
50% of 36 is 18
2
x/48 = 75/100
x/48 = 3/4
x= 48(3/4)
x=30
3
x/30 = 60/100
x/30 = 3/5
x = 30(3/5)
x = 6
4
rate = boxes per day per person
r = 1500/4/6
r=62.5
62.5 = x/6/8
500 = x/6
3000 = x
5
rate = task per day per worker
r = 1/7/5
r=0.02857142857
0.02857142857 = 1/x/7
0.2 = 1/x
0.2x = 1
x = 0.2
1/0.2 = 5
Answer:
13x^2 - 7x + 6
Step-by-step explanation:
(9x^2 -7x) - 1(-4x^2 + 6)
(9x^2 -7x) + 4x^2 +6
9x^2 - 7x + 4x^2 + 6
(9x^2 + 4x^2) - 7x + 6
13x^2 - 7x + 6
Hi!to calculate a square root without a calculator is to see if you can get to that whole number by squaring smaller numbers,or multiplying a smaller number by it self.
