Miranda needs to add 68 + 19 mentally but is struggling. If she knows that 68 + 20 = 88, how can she use this to help?

1 answer:

7 0

She can use 68 + 20 = 88 to help by noticing that the 20 is ahead of 19 by 1. She can easily mentally turn the 20 into a 19 and realized that the 88 would become 87.

Social studies Geometry P.11 Similarity and altitudes in right triangles CEZ You have priz If SU = 28 and UV = 6, what is TU? T

Alex777 [14]

Answer:

TU ≈ 12.96

Step-by-step explanation:

Using the Altitude on Hypotenuse theorem

(leg of outer triangle)² = (part of hypotenuse below it) × (whole hypotenuse)

TU² = UV × SU = 6 × 28 = 168 ( take square root of both sides )

TU = $\sqrt{168}$ ≈ 12.96 ( to the nearest hundredth )

Step-by-step explanation:

2ya and 2yb where a and b have no common factors and a and b are polynomaals

a=(x+2)(x+3)

b=(x+4)(x+5)

no common factors betwen a and b

2ya=2y(x+2)(x+3)=2yx²+10xy+12y

2yb=2y(x+4)(x+5)=2yx²+18xy+40y

the 2 polynomials are 2yx²+18xy+40y and 2yx²+10xy+12y

18. Find two numbers whose L.C.M is 3965 and G.C.F is 61

Artist 52 [7]

Answer:

305 and 793

Step-by-step explanation:

LCM * HCF = product

3965 * 61 = 241,865 = 5*13*61*61

HCF = 61 so

61*5 = 305

61 * 13 = 793
