I’m going to guess E. But i think i might be really really wrong
5x/6=20
5x=20*6
5x=120
5x/5 = 120/5
x=24
Answer:
Step-by-step explanation:
9-3/4 x (3/5÷1/8) =
9 - 0.75 * (0.6 / 0.125) =
9 - 0.75 * 4.8 =
9 - 3.6 =
5.4
Base=x+7 Height=x Area=60. 60=((x+7)(x))/2----->60=(x^2+7x)/2
120=x^2+7x X^2+7X-120=0. QUDRATIC FORMULA: -7+/- SQRT(49+480)/2
(-7+/-23)/2... 8 and -15. -15 ISNT the answer because you cant have a negative length. X=8 Base=8+7---->15 Height=8
For odd integers,
(2x+1)=odd
.
3 consecutive odd integers,
x + (2x + 1) + (4x + 1)
= 7x + 2
