The difference of Vidya’s height and 15 is 74?

Luba_88 [7]

Answer: V - 15 = 74; V = 89

Step-by-step explanation:

"difference" means subtraction

"is" means equals

Vidya's height minus 15 is 74

V - 15 = 74

To solve, add 15 to both sides: V - 15 + 15 = 74 + 15

V = 89

An investment of 11,000 is made into an account that earns 4.25% annual compound interest for 30 months. Assuming no other depos

LenKa [72]

Answer:

It should be $12168.75

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year,

then, solving our equation

I = 11000 × 0.0425 × 2.5 = 1168.75

I = $ 1,168.75

The simple interest accumulated

on a principal of $ 11,000.00

at a rate of 4.25% per year

for 2.5 years is $ 1,168.75.

1,168.75 + 11000 = 12168.75

What is the difference of the polynomials? (8r6s3 – 9r5s4 + 3r4s5) – (2r4s5 – 5r3s6 – 4r5s4)

nignag [31]

(Distribute the minus sign of the subtrahend in each term.)
= 8r⁶s³ – 9r⁵s⁴ + 3r⁴s⁵ – 2r⁴s⁵ + 5r³s⁶ + 4r⁵s⁴
(Add or subtract like terms.)
= 8r⁶s³ – 5r⁵s⁴ + r⁴s⁵ + 5r³s⁶
(If you want to factor out, then...)
= r³s³ (8r³ – 5r²s + rs² + 5s³)
