Answer:
Step-by-step explanation:
Lets say Rhonda drove x miles, then Jamie drove 2x miles
x+2x=90
3x=90 divide each side by 3
x=30
so Rhonda drove 30 miles and Jamie drove 30*2=60 miles
Step-by-step explanation:
(2x +y)(3x²+y)
6x³ + 2xy² + 3x²y + y²
it is 1 gallon

The computation shows that the options that are greater than 90 include:
23 × 4
30 + 72
194 - 98
.
<h3>How to compute the value?</h3>
It should be noted that the thing to do is just to simplify the given numbers. This will be:
a. 23 × 4
= 92
b. 30 + 72
= 102
c. 3³ + 7²
= 27 + 49
= 73
d. 194 - 98
= 96
Therefore, the options that are greater than 90 include a, b, d.

choose all the measures greater than 90
a. 23 × 4
b. 30 + 72
c. 3³ + 7²
d. 194 - 98
x² = -7x + 4
x² + 7x - 4 = 0
x = -7 ± √(7² - 4(1)(-4))
2(1)
x = -7 ± √(49 + 16)
2
x = -7 ± √(65)
2
x ≈ -7 ± 8.06
2
x ≈ -3.5 ± 4.03
x ≈ -3.5 + 4.03 or x ≈ -3.5 - 4.03
x ≈ 0.53 or x ≈ -7.53
